this would actually have some solutions because
y=3.5x−3.5
Step: Substitute 3.5x−3.5 for y in y=−3.5x+3.5:
y=−3.5x+3.5
3.5x−3.5=−3.5x+3.5
3.5x−3.5+3.5x=−3.5x+3.5+3.5x(Add 3.5x to both sides)
7x−3.5=3.5
7x−3.5+3.5=3.5+3.5(Add 3.5 to both sides)
7x=7
7x
7
=
7
7
(Divide both sides by 7)
x=1
Step: Substitute 1 for x in y=3.5x−3.5:
y=3.5x−3.5
y=(3.5)(1)−3.5
y=0(Simplify both sides of the equation)
x=1 and y=0
