2 numbers that are equal have a sum of 60

Let's choose 2 arbitrary variables for the 2 numbers

x, y

Were given 2 equations:

- x = y <-- Because we have the phrase
*that are equal*
- x + y = 60

Because x = y in equation (1), we can substitute equation (1) into equation (2) for x:

y + y = 60

Add like terms to get:

2y = 60

Divide each side by 2:

2y/2 = 60/2

Cancel the 2's and we get:

y =

**30**

Since x = y, x = y = 30

x =

**30**
