Answer» Answer: Hope it's help you. mark me as brainlist. Step-by-step explanation: This can be SOLVED USING a SYSTEM of equations, where x is the first number and y is the second number. x + y = 40 x - y = 14 Combine the two equations via elimination and solve for x. (2x)/2 = 54/2 x = 27 Now substitute x into either of the original equations. (27 + y) - 27 = 40 -27 y = 13 (27 - y) - 27 = 14 - 27 (-y)(-1) = -13 (-1) y = 13 The two numbers that add up to 40 and have a difference of 14 are 27 and 13, respectively. |
