Answer:

Solution = -2x-7y=-4

Step-by-step explanation:

Add the x-component to the x-component, add the y-component to the y-component, add the number to the number.

It looks like this

5x + (-7x) = -2x

9y + (-2y) = -7y

1 + (-5) = -4

Then, put the solutions in the places where you see them in the equation, x goes first, y comes second, then this equals the number value.

-2x - 7y = -4
