How would you solve 3x + y = -14 -2x + y = 9
while showing all of the work

Step-by-step explanation:

3x + y = -14

-2x + y = 9

We'll try to find x

(-2x + y = 9) multiplied by -1 => -1(-2x+y=9) = 2x-y = -9

3x + y = -14

+2x -y = -9

+__________

3x + 2x +y -y = -14 - 9

5x = -23

x = -23/5

3x + y = -14  =>And now we can find y. Just plug in -23/5 for x

5y = -1

y = -1/5

Hope this helps ^-^
