10r-5r+3r-8r what the answer

r=0

Step-by-step explanation:

10r-5r=3r-8r

We move all terms to the left:

10r-5r - (3r-8r) = 0

We add all the numbers together, and all the variables

10r-5r - (-5r) = 0

We add all the numbers together, and all the variables

5r - (-5r) = 0

We get rid of parentheses

5r+5r=0

We add all the numbers together, and all the variables

10r=0

r=0/10

r=0
