6th Grade Properties of Equality

The addition property of equality states that if the same amount is added to both sides of an equation, then the equation is still true. Which choice shows this by using the starting equation n - 2 = 5

• n - 2 = 5 + 2

• n - 2 + 2 = 5 + 2

• n + 2 - 5

• n - 2 + 5 = 2

Which equation shows the subtraction property of equality by changing the equation a + 2 = 11

• a + 2 - 5 = 11 - 5

• a + 2 + 5 = 11 + 5

• a + 2 ÷ 5 = 11 ÷ 5

• a + 2 = 11

Balanced (or true) equations have the same value on both the left and right sides of the equal sign. Which equations are balanced?

• 3 + 5 = 9

• 3 + 5 = 8

• 3 + 5 = 5 + 3

• 3 + 5 - 2 = 8 - 2

• 3 + 5 - 7 = 3 + 5 + 7
