Question

(2x+14)+(7x+13)=180 find x show your work

Answer 1

Get rid of the parentheses because addition is commutative.
2x+14+7x+13=180
9x+27=180
9x=153
x=17

Answer 2

`(2x+14)+(7x+13)=180 \\ \\ 2x + 14 + 7x + 13 = 180 \ / \ simplify \ brackets \\ \\ 9x + 14 + 13 = 180 \ / \ simplify \\ \\ 9x + 27 = 180 \ / \ simplify \\ \\ 9x = 180 - 27 \ / \ subtract \ 27 \ from \ each \ side \\ \\ 9x = 153 \ / \ simplify \\ \\ x = (153)/(9) \ / \ divide \ each \ side \ by \ 9 \\ \\ x = 17 \ / \ simplify \\ \\`

The final result is x = 17.
