Question

The sum of two numbers is 11. Their difference is 1. Find the numbers. Help please

Answer 1

The numbers are 6 and 5

6 + 5 = 11

6 - 5 = 1

Answer 2

Equations

x + y = 11

x - y = 1 Add these two equations.

2x = 12 The ys cancel out. Divide by 2

x = 12/2

x = 6

x + y = 11

6 + y = 11 Subtract 6 from both sides.

y = 11 - 6

y = 5

Answer

x = 6

y = 5
