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)
