    \[\frac{-3}{7x}+\frac{5}{14x} = 1\]Multiply both sides by 14x to get rid of the fractions. Solve for x. \[4x+2y = 16\]\[x+y=4\]Multiply the second equation by -2, add to the first. Solve for x. \[2x+y=24\]\[5x-y=-3\]Add the two equations. Solve for x. \[5x=3-10x\]Add 10x to both sides. Simplify to solve for x. You need to actually *do* the problems to learn anything...do you have trouble doing them, or do you not understand what to do?

    I've described what to do for each of the problems. Try to do what I suggested, and post your work.

    So, what do you get for the first equation after you multiply everything by 14x?

    Do you see why I chose 14x, and not say 7x or 9x?
