What you want to look for is a way to make the coefficients of either x or y the same (in absolute value). That way when you add or subtract the two equations, you will get a coefficient of 0 for that variable, which will allow you to solve for the other variable. The best way to do start is to find a variable where the coefficient in one equation is the multiple of another. In this case, 2-> one of the coefficients of y, multiplied by 5 = 10, the other coefficient of y.
In order to keep the second equation true, you need to multiply both sides of the equation by 5. So the second equation becomes
Subtracting the second equation from the first, you get 11x+0y=77
solving for x, x=77/11, so x=7, and plugging back into the original equation (or really just solving the second equation for y), you find that y is 7 also.
