The students in Mr.​ Kim's class are discussing how to apply the properties of equality. Jared started with the equation 10 - 4=6. He said that he could subtract 3 from the right side and then subtract 3 from either the 10 or the 4 on the left side to keep the equation balanced. Is Jared​ correct?

Answer:

Jared is right.

Step-by-step explanation:

proof 1:

10 - 4 = 6

6 = 6

second proof:

10-3 - 4 = 6 - 3

10 - 7 = 3

3 = 3

third proof:

10 - 4 - 3 = 6 - 3

10 - 7 = 3

3 = 3

Hence for all LHS = RHS proved and Jared is correct.
