# algebra

Dorothy is thinking of two numbers. The sum of the numbers is 40 and the difference is 6. write a system of equations and use elimination method to find the two numbers.

1. x + y = 40

x - y = 6

Add the two equations and solve for x. Insert that value into one of the equations to find y.
