Answer 1

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
