Answer:
27
Step-by-step explanation:
X/39=(X+18)/65
65X=39X+702
26X=702
X=27
6=-3(x+2)
——Distribute -3(x+2)
6=-3x-6
—-Flip the equation
-3x-6=6
—-add 6 on both sides..the 6’s will cancel each other and 6+6=12
-3x=12
—-divide -3 on both sides..the 3’s will cancel each other and 12 divided by -3 = -4
Answer: x = -4
