Question

-4 = r/20 -5
Solve for r. Show your steps​

Answer 1

r = 20

Step-by-step 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

Answer 2

-4 = r/20 - 5

Add 5 to both sides

1 = r/20

Multiple by 20 on both sides

20 = r
