-4 = r/20 - 5

Add 5 to both sides

Answer:

r = 20

Explanation:

-4 = r/20 - 5

  • Simplify both sides of the equation

-4 = r/20 - 5

-4 = 1/20r + -5

-4 = 1/20r - 5

  • Flip the equation

1/20r - 5 = -4

  • Add 5 to both sides

1/20r - 5 + 5 = -4 + 5

1/20r = 1

  • Multiply both sides of the equation by 20

(20)1/20r = 1(20)

  • r = 20
