Understand Simple Equations before you start

Read this if you're new to the topic—it will help you know what to do in each problem.

In an equation like x + 7 = 12, we want to find x. Do the opposite operation on both sides: subtract 7 from both sides, so x = 12 − 7 = 5.

Check: 5 + 7 = 12 ✓. So the answer is x = 5.

Examples

x + 7 = 12 → x = 5

x + 3 = 9 → x = 6
