25x (square) plus 40 plus 15 equals 680.
It is: 40/10 = 15/100 = 4.15

60
Substitution method: from first equation y = 5x - 8. In the second equation this gives 25x - 5(5x - 8) = 32 ie 25x - 25x + 40 = 32 ie 40 = 32 which is not possible, so the system has no solution. Multiplication method: first equation times 5 gives 25x - 5y = 40, but second equation gives 32 as the value of the identical expression. No solution.
Simply put multiply 15 by 40 to get the square footage. This would be 600 square feet.
