Question 692568
The first thing you want to do in order to solve for m, is use the distributive property and multiply the 2 by everything in the parenthesis:


-3m + 2(2 + 2m) = -1  ---->  -3m + 4 + 4m = -1


Next, add -3m to 4m, which gives us:


m + 4 = -1


Finally, subtract 4 from both sides of the equation, so that m is by itself on the left, and what m equals, is on the right side:


m = -1 + -4 ---->  m = -5


Answer:  m = -5
