Question

■ Write an equivalent expression.

1 (12x+
(12x + 6x − 21) =
?
x
3
?

Answer 1

6x - 7

Explanation:

`(1)/(3)` (12x + 6x - 21 ) ← multiply each term in the parenthesis by
`(1)/(3)`

= 4x + 2x - 7 ← collect like terms

= 6x - 7

Answer 2

Hey there!

ORIGINAL EQUATION:

1/3(12x + 6x - 21)

COMBINE the LIKE TERMS

= 1/3(18x - 21)

DISTRIBUTE 1/3 WITHIN the PARENTHESES:

= 1/3(18x) + 1/3(-21)

SIMPLIFY:

= 6x - 7

Therefore, the answer should be:

6x - 7

Good luck on your assignment & enjoy your day!
