Answer: x= 5 years and y = $225
Step-by-step explanation:
Since we have given that
Amount Nisa gained per year = $25
Amount Kevin lost per year = $35
According to question,

so, it becomes,

so, For x= 5 years,
Their income of Nisa and loss of Kevin will be

Y=mx+b
m=slope
b=yintercept
slope=-3/4
yintercept=3/2
y=-3/4x+3/2
it could also be written
3x+4y=6
The answer is 5. The only factors are 1 and 5, and 5 is the highest.
4x - y = 10, y = 2x - 2
4x - (2x -2) = 10
4x - 2x + 2 = 10
2x = 8
x = 4
4(4) - y = 10
-y = -6
y = 6
So x = 4 y= 6
Hope this helps!
