X=60 and y=20
x and y can be many things that answers the question to 120
Lets see together how it gets done
120 180
160 200
200 220
240 240
so the answer is 3 months
Let the smallest integer be x
The second integer = x + 2
The third integer = x + 4
x + x + 2 = x + 4 + 24
2x + 2 = x + 28
2x - x = 28 - 2
x = 26
So the numbers are 26, 28, 30
Substitute the value for y as 450
450=-5x+1
Solve for x
450-1=-5x
449=-5x
89.8=-x
x=-89.8
