1 answer:
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
