Question 177801
Let x=amount of gallons that Alan's tank can hold
So x/4 +6=5x/8  multiply each term by 8
2x+48=5x  subtract 2x from each side
2x-2x+48=5x-2x  collect like terms
3x=48  divide each side by 3
x=16 gal-------------------------------amount that gas tank holds

(1/4)*16=4
4+6=10
10=(5/8)*16
10=10
