Question

solve for r. 17r - 13r = 20 r = submit

Explanation:

Step1: Combine like terms

$17r - 13r = (17 - 13)r = 4r$
So the equation becomes $4r = 20$.

Step2: Solve for r

Divide both sides of the equation $4r = 20$ by 4:
$\frac{4r}{4} = \frac{20}{4}$
Which simplifies to $r = 5$.

Answer:

$r = 5$
