Question

Use the terms 4, 12a 6 2a and 24 to make equivalent expressions use each term only once use substitution to prove that the expressions are equivalent

Answer 1

12a + 24 = 6(2a + 4)

Explanation:

Given the numbers :

4, 12a 6 2a and 24 ; create an equivalent expression :

12a, 2a, 4, 6, 24

We could separate tbe constant terms and those with variables :

12a, 2a ; 6, 4, 24

We could put the larger digit to one side

12a + 24 = 6(2a + 4)

This way the Right hand side is equal to the left hand side.

Check:

12a + 24 = 6(2a + 4)

12a + 24 = 12a + 24

Hence, the proof
