Help Very Much Needed !Solve For X In The Diagram

x = 10

Step-by-step explanation

The exterior angle = the sum of the 2 interior angles (which is the other way to solve the other problem you just posted.)

-10 + 14x = 60 + 7x            Add 10 to both sides

-10+10+14x =60+10+7x     Combine

14x = 70 + 7x                     Subtract 7x from both sides

14x-7x = 70+7x-7x             Combine

7x = 70                              Divide by 7

7x/7 = 70/7

x = 10
