Answer:

1 solution

Step-by-step explanation:

-5 - 11r = 6 ( -2r - 3 )

Distribute:

-5 - 11r = -12r - 18

Add 18 to both sides:

13 - 11r = -12r

Add -11r to both sides:

13 = -r

Divide each side by -1:

-13 = r

1 is your answer

Hope this helps!

-5 + (-11r) = -12r - 18

By adding 5 to both sides you remove -5 on the left side and end up with:

-11r = -12r -13

By adding 12r to both sides you get rid of the -12r on the right side and get:

1r = -13

This is the same as:

r = -13

So this would only be 1 solution.
