Answer:

x=5, y=-3

Step-by-step explanation:

we can find the answer by plugging in x=3y+14 to the second equation

5(3y+14)-2y=31

simplify

15y+70-2y=31

13y=-39

y=-3

now, plug in this to the initial equation x=3y+14

x=3(-3)+14

x=-9+14

x=5

Answer:

x = 5

y = -3

Step-by-step explanation:

x - 3y = 14

5x - 15y = 70

5x - 2y = 31     subtract these two equations

    -13y = 39

        y = -3

x - 3(-3) = 14

         x = 5
