Answer:

39+31=70

70+(11x+11)=180

70-70+(11x+11)=180-70

11x+11 = 110

11x+11-11 = 110-11

11x = 99

11x/11 = 99/11

x = 9

Answer:

x=9

Explanation:

31+39+11x+11=180

Simplify both sides from the equation:

(11x)+(31+39+11)=180 (combine like terms)

11x+81=180

Subtract 81 from both sides

11x+81-81=180-81

You end up with:

11x=99 (Divide both sides by 11)

x=9
