5x - 14 = 8x + 4

• x = 6
• x = -6
• x = -18/13
• x = 10/3

10x + 9 = 4x - 9

• 0
• 3
• -3
• -18

Solve for the variable.

8-3a+12=2a

• a = 4

• a = 1

• a = 3

• a = 5

What is the first step to solve this equation?

3x + 6 = 10 + 3x + 4x 

• Add 4x to both sides of the equation

• Combine like terms 3x and 4x on the same side of the equation

• Add 3x and 6 to get 9x

• Add 6 and 10 to get 16

Solve the equation
4x - 5x + 9 =5x - 9

• x = -3
• x = 9
• x = 3
• x = -9

• x = 1

• x = 2

• x = 1/2

• x = 3/2

How do you undo addition?

• divide

• multiply

• subtract

• add

What is the first step in solving this equation?

2x + 3 - 5x = 15x - 10

• parentheses

• combine like terms

• add 10

• move the 2x

Combine all like terms.

4x + 5x - 7= 8 - 3x -6x

• 16x = 8 -3x -6x

• 9x - 7 = 8 - 9x

• nothing can be combined

4x - 8 + 3x + 5 = 2 + 5x - 15

• x = 10

• x = -5

• x = 3

• x = -4
