Question

Help solve for r algebra

Answer 1

`(20)/(7)`

Explanation:

Multiply both sides by 7 to get rid of the denominator on the Right Side (RS). Do the same for the left side (LS) by multiplying both sides by 5 to get:

`7r=4(5)`

Simplify:
`7r=20`

Divide both sides of the equation by 7 to get:
`r=(20)/(7)`
