X = 2.61 , Y = -0.7
Step-by-step explanation:
1. It mentions simultaneous equation so all you have to do is see where the two lines intersect.

correct me if i’m wrong
Seven and five because seven times five is thirty five and seven minus five is two
Y=3.5x+4
a) 5=3.5x+4, 3.5x=1, x=1/3.5=2/7
b) y=3.5*10+4=35+4=39
-4,0
2,0
both are true because they do not have a y coordinate, meaning they dont move off of the x-axis
