Introduktion til ligninger med variable på begge sider

Lær at løse ligningen 2x + 3 = 5x - 2, hvor der er variable på begge sider. Vi starter med at visualisere ligningen, hvorefter vi isolerer den variable ved at foretage de samme regneoperationer på begge sider. Til sidst løser vi ligningen og finder værdien af den variable. Lavet af Sal Khan.
