Answer:

(2,14)

Explanation:

Since y=5x+4, you can plug that into the other y in the other equation which would give you x+12=5x+4

Now subtract 12 from both sides

x=5x-8

Subtract 5x from both sides

-4x=-8

Now you divide them both by -4 which gives you x=2

Now plug x in to any of the equations

y=5(2)+4

y=10+4

y=14

Your final answer is (2,14)
