Solve for x.
r/4 + 9 = 5

A. x = -20
B. x = 56
C. x = -16
D. x = -12

Answer 1

There is no x in the equation, but r = -16.

Step-by-step explanation:

Our original equation is: r/4 + 9 = 5

If we ultiply both sides, we get: r + 36 = 20

Then we move the constance to the right: r = 20 - 36

And then we calculate to get: r = -16

Answer 2

multiply both sides of the equation by 4 then move the constant to the right-hand side and change its sign then calculate the difference and your answer is r= -16
