One & Two Step Equations

The goal in a one step equation is to isolate the variable in one math inverse operation. If you subtract 5 to isolate the variable what would x be equal to?

x + 5 = 12

• x = 6

• x = 7

• x = 10

• x = 3

The goal in a two-step equation is to isolate the variable using two inverse operations. Solve the equation: 2x + 7 = 15 using two inverse operations.

• x = 4

• x = 5

• x = 8

• x = 6

It doesn't matter whether the variable is on the left or right side of the equal sign. The goal is still to isolate the variable. Solve the equation: 18 = 6q

• q = 3

• q = 5

• q = 4

• q = 6

In the 2-step equation 2x - 8 = 12, the first step is to add 8 to make a zero pair on the left side of the equal sign and then add 8 on the right side of the equal sign to make 2x=20. What is the second step?

• Subtract 2 from both sides of the equal sign

• Multiply 2 from one side of the equal sign.

• Divide 2 from only the left side of the equal sign.

• Divide 2 from both sides of the equal sign.
