Question

Ex 1: The sum of two numbers is 93 and their difference is 41.
Find them.

Answer 1

Let x = the larger number
Let y = the smaller number
x + y = 93
x - y = 19 Add the two equations together.
2x = 112 Divide both sides of the equation by 2.
x = 56
56 + y = 93 Subtract 56 from both sides of the equations.
y = 37
