Question

Solve the equation -9=r over 4 (fraction)
A) r=36
B) r=13
C) r=9 over 4 (fraction)
D) r=-36

Answer 1

Try to do that by yourself, just multiply both members for "4", one cancels out, the other one..?

Answer 2

I tried, the answer i got was C. I just want to see if it right.

Answer 3

\[-9 = r \div 4\]

so to move the 4 to the other side and get r by itself you would need to multiply both sides by 4.

and \[-9\times4 = -36\]

Answer 4

Thank you
