7r=-7/2
divide both sides by 7 to get r by itself
(7r)/(7) = (-7/2)/(7)
if you don't quite see it, think of multiplying both sides by 1/7 instead (its the same thing as dividing by 7)
(7r)*(1/7)=(-7/2)*(1/7)
r=-1/2
Answer:
no solution
Step-by-step explanation:
X/3+2=x/3

X/3-x/3+2=x/3-x/3
2 = 0
This is never true so there is no solution
