Question

3(r + 8) = 72. Do I use the Distributive property and multiply 3 by r and 8 and then continue or do I subtract 8 first? Help please!

Answer 1

U have to distribute first so it would be:
3r+24=72
3r=48
r=16

Answer 2

Distributive property then subtract...think of it as going the opposite of pemdas when solving for a variable
3r+24=72
3r=48
r=16
