Help solve for r algebra

bija089 [108]

Answer:

$\frac{20}{7}$

Step-by-step 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: $r=\frac{20}{7}$
