Question:
how do u solve problems using systems of equations?
ex: First you should look at the answer Harley gave to a similar question that we received a while ago. For your system of two equations I would multiply the second equation by 2 so that the coefficient of y is 2. I made this choice because the coefficient of y in the first equation is 2. Thus the second equation become 84 = 8x + 2y As a check you should take x = 10 and the value of y you found and substitute them into the other of the two equations to verify that the solution you found satisfies both equations.
