Answer:

x = -3, y = 24

Step-by-step explanation:

y=−7x+3;y=−8x

Step: Solve y=−7x+3 for y:

y=−7x+3

Step: Substitute−7x+3 for y in y=−8x:

y=−8x

−7x+3=−8x

−7x+3+8x=−8x+8x(Add 8x to both sides)

x+3=0

x+3+−3=0+−3(Add -3 to both sides)

x=−3

Step: Substitute−3 for x in y=−7x+3:

y=−7x+3

y=(−7)(−3)+3

y=24(Simplify both sides of the equation)
