Answer:
For the first one, the answer is x=32
For the second one, the answer is x= -16
Step-by-step explanation:
-120+11x=3x+136 (subtract 3x from both sides)
-120+8x=136 (add 120 to both sides)
8x=256 (divide both sides by 8)
x= 32
-7x-50=-2x+30 (add 2x to both sides)
-5x-50=30 (add 50 to both sides)
-5x=80(divide both sides by -5)
x= -16
