Answer:
Step-by-step explanation:
r/9 = -4
then multiply 9 to -4 which equals -36
at last, r is equal to -36
So you need to have the variables on one side and the constants on another.
Since r is divided by 9 on the left side, you have to get rid of the 9 by multiplying. r/9 times 9 equals r, and -4 times 9 equals -36.
So r = -36
