Answer:

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

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!
