Question

Write an equation and solve for the value of x (please show work)

Answer 1

`7x-11+5x-1=180\\12x-12=180\\12x=192\\\boxed{x=16}`

Answer 2

x=16

Explanation:

The two angles form a straight line so they add to 180

7x-11 + 5x-1 = 180

Combine like terms

12x -12 =180

Add 12 to each side

12x-12 +12 =180+12

12x = 192

Divide each side by 12

12x/12 =192/12

x=16
