Question

1/3(12x 6x-21) write an equivalant expression

Answer 1

The equivalent expression for 1/3(12x + 6x - 21) is 6x - 7.

Step-by-step explanation:

To write an equivalent expression for 1/3(12x + 6x - 21), you need to distribute the fraction 1/3 across each term in the parentheses.

This means you multiply 1/3 by each term separately.

• 1/3 × 12x = 4x
• 1/3 × 6x = 2x
• 1/3 × -21 = -7

Now, combine these results to get the equivalent expression:

4x + 2x - 7

Lastly, combine like terms (4x and 2x) to further simplify:

6x - 7
