What is the value of x? Enter your answer in the box. x =

Answer:
x = 12
Step-by-step explanation:
(10x - 20) + (6x + 8) = 180
= 10x - 20 + 6x + 8 = 180
= 10x + 6x - 20 + 8 = 180
= 16x - 12 = 180
= 16x = 180 + 12
16x = 192
x = 192 / 16
x = 12
(10(12) - 20) + (6(12) + 8) = 180
100 + 80 = 180
180 = 180
