Answer: x = 21

Step-by-step explanation:

3x - 8 + x + 14 + 90 = 180

Bring like terms together

3x + x - 8 + 14 + 90 = 180

4x + 96 = 180

Subtract both sides by 96

4x = 84

Divide both sides by 4

x = 21

Answer:

x=21

Step-by-step explanation:

first you add like terms

3x-8+x+14+90=180

4x-8+14+90=180

4x+96=180

then you can subtract 96 from 180

4x=84

devide 84 by 4 to get x

x=21
