Linear Equations II — Solving for x

Step 4 of 9 · 18 min remaining

A linear equation keeps the variable to the first power. To solve, you isolate x by doing the same operation to both sides until x stands alone.

3x + 6 = 21 → 3x = 15 → x = 5

Notice each line keeps the equation balanced — subtract 6 from both sides, then divide both sides by 3. The next exercise gives you three to try on your own.
