How do you solve the equation: 4 + b = 30?

Back

Subtract 4 from both sides to isolate b: b = 30 - 4, so b = 26.

Front

How do you solve the equation: x + 12 = 20?

Back

Subtract 12 from both sides to isolate x: x = 20 - 12, so x = 8.

Front

How do you solve the equation: 17 = x + 3?

Back

Subtract 3 from both sides to isolate x: x = 17 - 3, so x = 14.

Front

How do you solve the equation: x - 62 = 123?

Back

Add 62 to both sides to isolate x: x = 123 + 62, so x = 185.

Front

What is the first step to solve the equation: x + 5 = 10?

Back

Subtract 5 from both sides.
