One-Step +/- day 2

Solving One-Step Equations +/-

Day 2

These are the steps to solving one-step equations.

• We need to get the variable (letter) all by itself.

• We use the inverse operation to get the variable (letter) all by itself.

• Inverse means opposite.

• Whatever we do to one side of the equal sign, we must also do to the other.

Multiple Choice

How do we get the variable "y" all by itself?

y + 7 = 10

• -7 from both sides

• +7 to both sides

• -10 from both sides

• +10 to both sides

Multiple Choice

Solve for the value of x.

x + 3 = 9

• x = 5

• x = 6

• x = 3

• x = 27

Multiple Choice

How do we get the variable "x" all by itself?

x - 5 = 14

• -5 from both sides

• +5 to both sides

• -14 from both sides

• +14 from both sides

Multiple Choice

Solve for the value of y.

y - 4 = 8

• y = 4

• y = 12

• y = 16

• y = 1
