-4 = r divided by 20 − 5 Solve for R

Mathematics
1 answer:
Sidana [21]3 years ago
6 0

Answer:

20

Step-by-step explanation:

Simplify both sides of the equation.

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

Flip the equation.

1 /20 r−5=−4

Add 5 to both sides.

1 /20 r−5+5=−4+5

1 /20 r=1

Multiply both sides by 20.

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

r=20
