Solve by elimination.

5x-7y=19

7x-7y=-7

(x, y) = (-13,-12)

Step-by-step explanation:

5x - 7y = 19

7x - 7y = - 7 Multiply both sides of the equation by - 1

Which then gives you:

5x-7y=19 Sum the equations vertically to eliminate

-7x+7y=7 at least on variable

-2x=26 Divide both sides of the equation by - 2

X=-13 Substitute the given value of x into the equation 7x - 7y = -7

7 x (-13) - 7y=-7 solve the equation for y

y=-12

Thus gives you (-13,-12)
