Question

3x+18+4x+15=180 what is x

Answer 1

You’ll combine like terms, then you have to isolate x on one side of the equal sign. Then solve

Answer 2

x = 21

Explanation:

Adding numbers:

3x+ 18 + 4x + 15 = 180

3x + 33 + 4x = 180

Combine Like terms:

3x + 33 + 4x = 180

7x + 33 = 180

Subtract:

7x + 33 - 33 = 180-33

7x = 147

Divide:

`(7x)/(7) = (147)/(7)`

x = 21
