Let 'x' be one of the numbers 'y' be the other number ---------------------------------- -the sum of two numbers is 15 x + y = 15 -----equation 1 ------------------------ -three times one of the number is 19 less than 5 times the other 3y = 5x - 19 -------equation 2 ------------------------ From equation 1 x + y = 15 x = 15 - y ---equation 1' ----------------------- Substitute equation 1' to equation 2 3y = 5x - 19 3y = 5(15-y) - 19 3y = 75 - 5y - 19 Transpose -5y to the left side of the equation 3y + 5y = 75 - 19 8y = 56 y = 7 ------------------- Substitute y=7 to equation 1' x = 15 - y x = 15 - 7 x = 8 ------------------ Therefore the two numbers are 7 and 8.
