Question

One of the steps Kim used to solve an equation is shown below.

4x−6=22
4x-6+6=22+6
Which statement describes the procedure she used in this step and identifies the property that justifies the procedure?
PLS help :(
A: Kim subtracted 6 from both sides of the equation. This procedure is justified by the additive property of equality.B:Kim added 6 to both sides of the equation. This procedure is justified by the additive inverse.C:Kim added 6 to both sides of the equation. This procedure is justified by the additive property of equality.D:Kim subtracted 6 from both sides of the equation. This procedure is justified by the additive inverse.Description

Answer 1

Alrighty, so, 4x-6=22 is the original equation.
This means that Kim has to add 6 to both sides of the equation. Knowing this leaves us with answers B.) and C.) because A.) and D.) say that Kim subtracts 6.
The Additive Property of Equality says that if you add the same number to both sides of an equality then the sides continue to be equal to each other. This is exactly what happened in the equation so C.) is your answer.

Hope this helps! (:
