Solve the system using the addition method. state your solution as an ordered pair.

3x+2y=56
9x-2y=4

The solution as an ordered pair is (-11/9, -15/2)

Step-by-step explanation:

Multiply the first equation by -3.  The resulting system is then

-9x - 6y = 56

9x - 2y = 4

 -8y = 60, or y = -7.5.  From the second equation and this result y = -7.5, we know that 9x - 2(-7.5) = 4, or 9x = -15 + 4, or 9x = -11.  Then x = -11/9.  The solution as an ordered pair is (-11/9, -15/2).

answer: x=60
