Combing Like Terms with Distribution Rational Numbers

Simplify the following expression:
-10x + 15 - 3x + 2

• 13x² + 17

• -13x² + 13

• -13x + 17

• -7x + 17

Simplify the following expression:
-7x +5 (1 - 8x)

• -33x + 5

• 5 + 33x

• 47x + 5

• 5 - 47x

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

Solve for x using combine like terms:

4x + 5x + 7 – 3x + 5 = –18

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. Distribute then Combine Like Terms:

–4 (3x – 7) = 4

Solve for x:

4(2 – x) +2x = 13 – 3x

When distributing a number through ( ), it needs to multiply to __________________

• just the first term inside the ( )

• just the last term inside the ( )

• every term inside the ( )

• any two terms inside the ( )

Solve the equation below. Distribute FIRST and then combine like terms:

3 (4 – 2x) + 4x = 2

• x = 5

• x = 1

• x = –1

• x = –5
