Answer:
(x,y) = (-2, -1)
Step-by-step explanation:
We start off by substituting the value of "x".
5x+7y=-17
x=-[tex]\frac{5}{4} + \frac{3}{4}y[/tex]
We then solve 5[tex]5(-\frac{5}{4}+\frac{3}{4}y ) +7y= -17[/tex]
y=-1 *Substitute the value of "y"
x= -[tex]-\frac{5}{4}+\frac{3}{4}x(-1)[/tex]
x=-2
[tex]\left \{ {{-17=-17} \atop {-5=-5}} \right.[/tex] This works.
