Answer:

y = 16x + 4

y = 25x - 23              

____________

16x + 4 = 25x - 23

27 = 9x

3=x

__________

y = 25(3) - 23

y = 75 - 23

y = 52

_________

They will intersect at (3, 52)

Step-by-step explanation:

The second step which is bolded I simplified the equation. In the next step I'm going to substitute 3 into the second equation.
