Solve this system of equations using the substitution method y=5x+4 x+12=y
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
Subtract 5x from both sides
Now you divide them both by -4 which gives you x=2
Now plug x in to any of the equations
Your final answer is (2,14)
