multiply the top by 7
OpenStudy (tad1):
Multiply the top equation by 7 so it becomes 14x + 70y =406. Then add the two equations together by combining like terms. The x terms will disappear or be eliminated. And you will have one equation with y as the only variable. solve this equation for y. Then substitute the result back into one of the original equations to find x. It's always a good idea to check your answer in the other equation.
