Lær at løse ligninger

Her lærer du en systematisk måde at løse ligninger på, der ruster dig til at kunne løse mere komplicerede ligninger.

Sådan løses ligninger hvor der indgår logaritmer og potenser.

Learning how to solve basic linear equations is critical in math, especially in Algebra. Many students struggle with solving equations because they don’t really understand how to solve more basic equations. This video will explain in detail how to solve basic algebra equations and will review how to use the Distributive property and combine like terms when solving an equation.
