a) divide by 2 on both sides to solve for x. When you divide by 2 in this case, all you have to do to the fraction is multiply the bottom by 2.
x=3/8
b) to solve for m, multiply by 3 on both sides. This will multiply only the 2 by 3.
m=-6/5
c) You don't have a variable to solve for written in this problem, did you make a typo?
