If your substituting for y what Is the ordered pair for 5x+3y=-19and y=7

Question

5?+3? =-19

?=7 

Answer 1

It seems that you want to find the coordinates of the line.

 

5x+3y = -19

 

5x+3(7) = -19

5x+21 = -19

5x = -40

  x = -8

 

Your ordered pair is (-8, 7).

Answer 2

5x + 3y = -19

5x + 3(7) = -19

5x + 21 = -19

5x = -40

x = -8

 

(-8, 7)
