Question

Help plz 6r – 12 = 6

Answer 1

the answer is 3  

6r = 6+12 
6r = 18
18/ 6 = 3

r = 3

Answer 2

Ok so to solve for r you need to isolate the variable. This is what you do.

6r - 12 = 6 
Add 12 to both sides.
6r = 18
Divide.
r = 3
Lets check our answer.
6(3) - 12 = 6
18 - 12 = 6
6 = 6 It makes sense so r = 3 is the answer.
I hope this helps love! :)
