Answer:
x = -3
Step-by-step explanation:
-2x + 14 = 20
Subtract 14 from each side.
-2x = 6
Divide both sides by -2
-3
First, subtract 14 from 20. 20-14=6. And then divide -2 on each side. You then have to do 6/-2, when a postive number divides a negative, you change the sign. So you would get x=-3
_ ÷ 7=9
_ - 12=0
25 ÷ 3=y
1/5×r=15
(2 × y) - 6 =34
