What is the goal when solving one-step equations?

Back

The goal is to isolate the variable on one side of the equation to find its value.

Front

How do you solve the equation y + 10 = 22?

Back

Subtract 10 from both sides: y = 22 - 10, so y = 12.

Front

How do you solve the equation x + 7 = 18?

Back

Subtract 7 from both sides: x = 18 - 7, so x = 11.

Front

How do you solve the equation 20 = x - 3?

Back

Add 3 to both sides: x = 20 + 3, so x = 23.

Front

How do you solve the equation 6 + z = 14?

Back

Subtract 6 from both sides: z = 14 - 6, so z = 8.

Front

How do you solve the equation b - 4 = 9?

Back

Add 4 to both sides: b = 9 + 4, so b = 13.
