The difference of two numbers is 15 five times the smaller is the same as 9 less than twice the larger find the number?
Call the numbers x and y (x>y) "The difference of two numbers is 15." x - y =15 "Five times the smaller is 9 less than twice the larger." 5y = 2x - 9 From the first equation, y = x-15 Substitute into the second: 5(x-15) = 2x - 9 expand: 5x - 75 = 2x - 9 collect terms: 5x - 2x = 75 - 9 simplify 3x = 66 x = 22 y = x-15 = 22-15 = 7 (x,y) = (22, 7)

What is the sum of two numbers is 37 and their difference is 7 find the numbers?
Answer:22, 15.Solution:Suppose the first number is x, second one is y, then x + y = 37, x - y = 7.adding these equations:x + y = 37+x - y = 7_____________2 x + 0 = 44x = 44/2 = 22now substitute in first equation:22 + y = 37y = 37 - 22y = 15so the numbers are: 22 and 15.
