Algebra I on Khan Academy: Algebra is the language through which we describe patterns. Think of it as a shorthand, of sorts. As opposed to having to do something over and over again, algebra gives you a simple way to express that repetitive process. It's also seen as a "gatekeeper" subject. Once you achieve an understanding of algebra, the higher-level math subjects become accessible to you. Without it, it's impossible to move forward. It's used by people with lots of different jobs, like carpentry, engineering, and fashion design. In these tutorials, we'll cover a lot of ground. Some of the topics include linear equations, linear inequalities, linear functions, systems of equations, factoring expressions, quadratic expressions, exponents, functions, and ratios.

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

Learn how to solve multi-step equations. These equations contain parenthesis. The key to these multi-step equations is to get variables on one side of the equation and the constants on the other.
In this video I solved the following problems.
18 = 3(3x − 6)
37 = −3 + 5(x + 6)
10(1 + 3b) = −20

👉Learn how to solve a system of equations by substitution. To solve a system of equations means to obtain a common values of the variables that makes the each of the equation in the system true. To solve a system of equations by substitution, we solve for one of the variables in one of the equations and then substitute for the variable in the other equation and then solve for the other variable. Next we plug in the obtained value of the other variable into the equation for the initial variable we solved for to obtain the value of the variable.

The value of the two variables obtained is the solution to the system of equations.

👉 Learn how to solve literal equations. A literal equation is an equation where the unknown values are represented by variables. To solve a literal equation means to make one of the variables the subject of the formula. To do this, we use the simple algebraic process of undoing all the algebraic operations related to the variable we want to solve for.

In this lesson, you will learn how to solve fractional equations, which means that the variable may be in the denominator of one or more fractions.

This makes the equation much harder to solve because we must use the rules of fraction addition and fraction multiplication to isolate the variable. We will practice solving fractional equations by solving problems step-by-step.

Learn how to solve different types of linear equations (when the unknown is on one side of the equals sign).

In this lesson, you will learn how to solve multiple step (multi-step) equations in algebra. First, we explain how to isolate the variable to be solved for on one side of the equal sign by performing the opposite operation.

Next, the constant terms are moved to the other side of the equal sign. The result is that we have solved for the unknown value of the variable. In these equations, there is only one solution, but finding the solution requires multiple steps (operations).
