Answer:
x=-4
Step-by-step explanation:
These two angles have to equal 180 because they are opposite of each other. Therefore, the equation will be 129+x+x+59=180. You add all common terms. 2x+188=180. You want to isolate x so you have to subtract both sides by 188. Therefore, the equation will be 2x=-8. Divide both sides by 2 to isolate x. x=-8/2. This is equal to x=-4.

Answer:
11a-8
Step-by-step explanation:
Please Note that i assume 12a and 2 are positive.
(12a+2−8a+4)-(12−7a+2)
=12a+2-8a+4-12+7a-2
