Question

-6(2r+8)=-10(r-3)

Answer 1

Distribute the -6 throughout the parenthesis, same with the -10
So:
-12r - 48 = -10r +30

Then add 48 to both sides, then add 10r to both sides then divide by your remaining # in front of r and you'll have your answer.

Answer 2

-6(2r+8)=-6*2r+-6*8=-12r-48
-10(r-3)=-10*r-(-10)*3=-10r+30
now combine the similar terms
-12r+10r-48-30=-2r-78.
u can simplify and make it divide 2
so it will be r+39. ,so r=-39
