Combine Like Terms and Solve Equations

Solve by combining like terms:

2x + 4 = 3x – 6

Solve for x. Distribute then Combine Like Terms:

3(2x – 5) – 4x = –19

• x = –2

• x = 2

• x = 10

• x = –11

Solve for x by combining like terms:

2x + 9 + 4x + 3 = 5 + x + 12

• x = 1

• x = 3

• x = –2

• x = 4

In order for terms to be "like", they need to have the __________________

• same variable only

• same exponent only

• same variable and same exponent

• either same variable or same exponent

3y+6+4y-7=-8

• y=-1

• y=-8

• y=1

• y=7

What is the first step to solve the following equation?

12x + 4x = 64

• Combine Like Terms

• Subtract 64 from both sides

• Divide both sides by 12

• Subtract 16 from both sides

2m + 6m = 32

• m = 8

• m = 4

• m = -4

• m = -8

2x - 3 + 4x = 27

• 12

• 4

• 5

• 15

Solve for x:

-16 + 3n + n + 2 = 3n + 2n + 1

Solve: 5x - 4 + 2x = 3
