Question

If 9x - 7 + 19 + 3x - 1 = 180, what does x equal?

Answer 1

9x - 7 + 19 + 3x - 1 = 180 Given
12x + 11 = 180 Combine like terms
12x = 169 Subtract 11 from both sides
x = 14.0833 Divide both sides by 12

Hope this helps!

Answer 2

First combine like terms

9x + 3x = 12x

-7 - 1 + 19 = 11

12x + 11 = 180

12x + 11 (-11) = 180 (-11)

12x = 169

12x/12 = 169/12

x = 169/12

x = 14.083


x = 14.083 is your answer

hope this helps
