Answer:
point form: (3, 14) equation form: x=3, y=14
Step-by-step explanation:
if the equations are y=18x-40 and y=10x-16 solve y for 18x-40 by substituting 18x-40 for the y in y=10x-16.
18x-40=10x-16
18x-40+-10x=10x-16+-10x
8x-40=-16
8x-40+40=-16+40
8x=24
8x/8=24/8
x=3
then substitute 3 for the x in y=18x-40
y=18(3)-40
y=14
