Follow the directions to solve the system of equations by elimination.
8x + 7y = 39
4x – 14y = –68

To solve a system of equation by elimination, the coefficients of the  same variable of both equations must be equal. In this case, let's choose y.
In order to make the coefficient of y of the second equation be equal to 7, we divide it by 2. Resulting to:
2x - 7y = -34

Next, add the two solutions so that the y term is eliminated. The result is:
10x = 5
Then solve for x
x = 1/2

Substitute x to either of the solution to solve for y. The result is:
y = 5
