Question

What is the solution to the system of equations below?

Answer 1

Answer:

  (x, y) = (-4, -15)

Step-by-step explanation:

You can equate the expressions for y and solve for x.

  3/4x -12 = -4x -31

Adding 4x+12 gives ...

  (4 3/4)x = -19

  (19/4)x = -19

Multiplying by 4/19, we find ...

  x = -4

Substituting that into the first equation, we can find y:

  y = (3/4)(-4) -12 = -15

The solution is (x, y) = (-4, -15).
