Let the 2 numbers be x and y. y = x + 30 ( as the difference between the two numbers is 30) Sum of the two numbers = 100 => x + y = 100 => x + (x + 30) = 100                                            ( as y = x + 30 as shown above ) => 2x = 70 => x = 35      y = x + 30 = 65 Hope I helped! you may comment here if you have any further doubts and i will answer them :)

Let the two numbers be x and y. According to your question ; x + y = 100 x - y = 30 Thus. x = y + 30 Substituting the value of x, y + 30 + y = 100 2y + 30 = 100 y = 70 / 2 = 35 thus, y = 35 Substituting the value of y, x + y = 100 x + 35 = 100 x = 100 -35 = 65 x = 65. thus, the two numbers are 65 and 35.
