    Answer:

    1. x = 86

    2. x = 31

    3. x = 64

    4. x = 29

    Step-by-step explanation:

    1. 2x + 8 = 180

    -8 -8

    2x = 180 (divide both sides by 2 to get x by itself)

    2. 3x – 3 = 90

    + 3 +3

    3x = 93 (divide both sides by 3 to get x by itself. you divide because 3x is multiplying and you have to do the reverse operation)

    3. 2x -5 + x – 7 = 180 (you combine like-terms)

    3x -12 = 180

    +12 +12

    3x = 192 (you divide by 3 on both sides)

    4. x + 1 + x + 4 + x – 2 = 90 (combine like-terms)

    3x + 3 = 90

    -3 -3

    3x = 87 (divide both sides by 3)
