# Subtraction Property of Equality Examples

The subtraction property states that if we make subtraction on any one side of the equation, then it must make the same on the other side of the equation too. It can be stated in the form, if x = y, then x – 1 = y – 1. Here is subtraction property of equality example problems for your reference. For instance, if two pencil stands hold, 5 pens each, then while picking out 2 pens from one stand is made equal by taking another two pens from the second stand too.

###### Example 1:

Let us consider the equation: Solve subtraction property of equality for the equation: 2x+10=20.

###### Solution:

Step 1: Subtract both sides by constant 10. 2X +10 - 10 = 20 - 10

Step 2: Solve X: 2x = 10 x = 10 / 2 x = 5

###### Example 2:

Let us consider the subtraction property of equality example problem: Solve 8x + 40 = 100

###### Solution:

Step 1: Subtract both sides by constant 40. 8x + 40 - 40 = 100 - 40

Step 2: Solve X: 8x = 60 = 60 / 8 x = 7.5
