Answer:

x = -2

y = -10

(x, y) = (-2, -10)

Step-by-step explanation:

The question asks for us to solve using substitution.

In this case, we can substitute 5x for y:

3x - 2(5x) = 14

3x - 10x = 14

-7x = 14

Divide both sides by -7

x = -2

Plug -2 in for x to solve for y:

y=5x=5(-2)=-10

(x, y) = (-2, -10)
