Solve Equations with Combining Like Terms

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

3 (4 – 2x) + 4x = 2

• x = 5

• x = 1

• x = –1

• x = –5

Solve for x:

4(2 – x) +2x = 13 – 3x

6x - 5 + 7x = 34

x = ?

(Just type the number)

-15 + 3x - 7x = -43

x = ?

(Just type the number)

What is the first step to solve the equation?

• Distribute

• Combine Like Terms

• Collect Variables to One Side

• Use Subtraction Property of Equality

What is the first step in solving for the variable?

• Distributive property

• Combine Like Terms

• Move the variables to the same side

• Solve for the variable

3b + 6b = 63

• -7

• 9

• 7

• 21

7n-5n=6

• n=3

• n=7

• n=12

• n=-6

3x + 12 + 9x = 72

• 5

• 6

• 7

• -7
