Answer:

x=12

Explanation:

okay so how you would do this would be

1. since it equals 180 you have to write the equation

10x-20+6x+8=180

2. Then combine like terms

16x-12=180

3. then to find x you have to get rid of the other number (-12 here) so you add that to both sides

16x=192

4. then you divide by 16 to get rid of the 16 on the x

192/16

5. thus ur answer x=12

Answer:

x=12

Explanation:

we know that a full line would equal 180 degrees

because we have two angels, they must add up to the said 180 degrees

In the first equation, when 10x-20 is multiplied by 12 we get 120-20 resulting in 100 degrees

the second equation is 6x+8

We must follow the same rule of x=12

6*12= 72 + 8 = 80

when we add the two angels, we get 180 degrees.
