-4 + 8x = -20

move -4 to the other side

sign changes from -4 to +4

-4+4+8x=-20+4

8x=-20+4

8x=-16

divide both sides by 8 to get x by itself

8x/8=-16/8

answer:

x=-2

The answer is 17

This is because 1 + 2 must equal 180 as they are in a straight line.
So 4x + 2 + 110 = 180
Take away 110 from both sides
4x + 2 = 70
Take away 2 from both sides to get 4x = 68. Finally, divide both sides by 4 to get x = 17
