Question

How would you solve 3x + y = -14

Answer 1

Answer:

X=

$\frac{ - 23}{5}$

Y=

$\frac{ - 1}{5}$

Step-by-step explanation:

3x+y=-14

2x-y=-9

5x=-23

y=

Answer 2

Answer:

$x= \frac{-23}{5}, y=\frac{-1}{5}$

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

$3\frac{-23}{5} + y = -14$

$\frac{-69}{5} + \frac{5y}{5} = \frac{-70}{5}$

$\frac{5y}{5} =\frac{-1}{5}$

5y = -1

y = -1/5

Hope this helps ^-^
