What is the correct solution to this problem? a number divided by 3 is four more than –11. what is the number? a. –45 b. –21 c. -7/3 d. 45

If we add 4 to -11, we get -7

The problem says "A number divided by 3 is four more than -11" 

We have the number that is four more than -11 (which is -7). All we need to do is multiply -7 by 3 to get our answer (which is -21). 

We can show this in an equation where x = number we are finding

x/3 = (-11 + 4)

Multiply both sides by 3
x = 3(-7) = -21
