Track A takes 20 minutes
Track B takes 15 minutes
In 1 minute track be will do a fraction of 1/20, while track B will do 1/15
Both tracks in a minute = 1/20+1/15
= 35/300
Therefore the two tracks will take 300/35 minutes to fill the 200 cubic feet
That is 300/35
= 8.57 minutes
≈ 9 minutes

Simplifying
6.4n + -10 = 4.4n + 6
Reorder the terms:
-10 + 6.4n = 4.4n + 6
Reorder the terms:
-10 + 6.4n = 6 + 4.4n
Solving
-10 + 6.4n = 6 + 4.4n
Solving for variable 'n'.
Move all terms containing n to the left, all other terms to the right.
Add '-4.4n' to each side of the equation.
-10 + 6.4n + -4.4n = 6 + 4.4n + -4.4n
Combine like terms: 6.4n + -4.4n = 2n
-10 + 2n = 6 + 4.4n + -4.4n
Combine like terms: 4.4n + -4.4n = 0.0
-10 + 2n = 6 + 0.0
-10 + 2n = 6
Add '10' to each side of the equation.
-10 + 10 + 2n = 6 + 10
Combine like terms: -10 + 10 = 0
0 + 2n = 6 + 10
2n = 6 + 10
Combine like terms: 6 + 10 = 16
2n = 16
Divide each side by '2'.
n = 8

Simplifying: 4x + 52 + 8x + -10 = 90
Reorder the terms: 52 + -10 + 4x + 8x = 90
Combine like terms: 52 + -10 = 42 42 + 4x + 8x = 90
Combine like terms: 4x + 8x = 12x 42 + 12x = 90
42 + 12x = 90
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-42' to each side of the equation. 42 + -42 + 12x = 90 + -42 Combine like terms: 42 + -42 = 0
0 + 12x = 90 + -42
12x = 90 + -42
Combine like terms: 90 + -42 = 48
12x = 48
Divide each side by '12'. x = 4 from https://www.geteasysolution.com/4x+52+8x-10=90
