You can put this solution on YOUR website!
"Fuwa has $125 in $5 bills and $10 bills" ___ 5f + 10t = 125

"If he has four more $5 bills than $10 bills" ___ f = t + 4

substituting the equivalent value of f from the 2nd equation into the 1st equation ___ 5(t + 4) + 10t = 125

solve for t, then substitute back to find f
