What is the solution for -5x 7y11 and -5x 3y19?

Answer 1

-5x + 7y = 11 (1)

-5x + 3y = 19 (2) Subtract (2) from (1)

4y = -8 divide both sides by 4

y = -2 (the y-coordinate of the solution point)

Replace -2 for y at one of the given equations, let's say at (2).

-5x +3(-2) = 19

-5x - 6 = 19 add 6 to both sides

-5x = 25 divide both sides by -5

x = -5 (the x-coordinate of the solution point)

Thus, the solution point is (-2, -5).
