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:
Step-by-step explanation:
|2x-3|≤9
so -9≤2x-3≤9
add 3 to each inequality
-6≤2x≤12
divide by 2
-3≤x≤6
