What is 6r+70=-2 (35+3r)

6r+70=-2 (35+3r)

multiply the bracket by - 2

(-2) (35) = -70

(-2) (3r) = -6r

6r+70=-70-6r

move - 70 to the left side

sign changes from - 70 to + 70

6r+70-70=-70-70-6r

6r=-70-70-6r

move-6r to the left side

6r=-140-6r

move - 6r to the other side

6r+6r=-140-6r+6r

12r=-140

divide both sides by 12

12r/12=-140/12

r=-140/12

reduce - by dividing by 4

-140/4=-35

12/4=3

Answer:

r = - 35/3 and r=-11 2/3
