Question

the sum of two numbers is 40. when 3\1\4 times the larger number is subtracted from5\1\2 times the smaller, the difference is-25. find the two numbers.

Answer 1

Explanation:

Not a very well written or posted question, but here is what I think it means:

x+ y = 25 re-arange to y = 25-x and sub into the next equation:

5.5 y - 3.25 x = -25

5.5 (25-x) - 3.25 x = - 25

137.5 - 5.5 -3.25x = -25

x= 18 4/7 then y = 6 3/7
