What is the value of x? Enter your answer in the box. x =

Answer 1

Answer:

x=12

Step-by-step explanation:

Both these angles are *supplementary* to each other, this means that (10x-20) and (6x+8) will both equal 180 degrees.

1. Add 10x - 20 and 6x + 8 together

By adding them together, you get 16x - 12

2. Since both of them added together would also equal 180, this means that 16x - 12 = 180

3. Use the additive inverse property and add 12 to both sides. This gives you 16x = 192

4. In order to isolate x, divide 16 on both sides.

192/16 = 12

Therefore, x is 12

Answer 2

10x-20=6x+8
+20 +20

10x=6x+28
-6x -6x

4x=28

=7

Sorry if i’m wrong
