    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
