Solve by elimination.<br> 5x-7y=19<br> 7x-7y=-7
SVEN [57.7K]

Answer:

(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)

Hope this was useful!!! Sorry if it's wrong.
