One and Two Step Equations

What would be the best first step to solving the equation?
25 = 2x + 5

• add 3 to both sides

• subtract 5 from both sides

• add 5 to both sides

• subtract -5 from both sides

The GOAL when solving an equation is to....

• isolate the variable.

• check the solution.

• guess and check.

• Combine Like Terms.

Solve for x:
8x - 10 = -34

• 4

• 3

• -3

• -24

What is the first step in solving this equation:
5x + 7 = 12

• Divide by 5

• Subtract 5

• Multiply by 7

• Subtract 7

Solve  9 + x = 10

• 19

• 1

• 10/9

• -9

4x = 72

• x = 18

• x = 68

• x = 288

• x = 62

z - 33 = 234

• z = 267

• z = 231

• z = 317

• z = 281

x + 4 = 11

6x = 6

• 36

• 1

• 12

• 0

-12 = -4x

• x = 3

• x = -3

• x = 4

• x = -4
