<h2>Answer:</h2>
x+10y
<h3>Step-by-step explanation:</h3>
3x+2y+(-2x)+8y
First of all you cannot substitute x with y, so what u do u make the numbers with the same letters they have,and I put -2x because + & - equals to -(minus) :-
3x-2x+2y+8y= x+10y
I don't add 1 to x coze when x alone stands for 1, I added +10y because both the y equations had + they were positive so I add a +.

In order to find the volume of the tank, you just need to use this formula :
V = π r^2 h
r = 101.5 ft (half the diameter)
h = 25 ft
V = π (101.5)^2 x 25
= 809462.5 ft^3
