Answer: x≈ 14 . 08

Step-by-step explanation:

Given :

3x - 1 + 9x - 7 + 19 = 180

The first thing is to collect the like term , then we have

3x + 9x - 1 - 7 + 19 = 180

12x + 11 = 180

subtract 11 from both sides

12x = 180 - 11

12x =169

divide through by 12

x = 169/12

x = 14.083333333333

x≈ 14 . 08
