Question

3(2x−7)+ 1/ 3 (7x+2)

Answer 1

Step-by-step explanation:

Hey there!

Given;

= 3(2x-7) + 1/3(7x+2)

Let's simplify them.

$= 3(2x - 7) + \frac{1}{3} (7x + 2)$

$= 6x - 21 + \frac{7x + 2}{3}$

$= \frac{3(6x - 21) + 7x + 2}{3}$

$= \frac{18x - 63 + 7x + 2}{3}$

$= \frac{25x - 61}{3}$

Therefore the answer is (25x-61)/3.

Hope it helps...

Answer 2

Answer:

$\quad \frac{25x+2}{3}-21$

Step-by-step explanation:

$3(2x-7)+ 1/ 3 (7x+2)\\\\\mathrm{Expand}\:3\left(2x-7\right):\quad 6x-21\\=6x-21+\frac{1}{3}\left(7x+2\right)\\\\\mathrm{Expand}\:\frac{1}{3}\left(7x+2\right):\quad 7\times\frac{1}{3}x+2\times \frac{1}{3}\\\\=6x-21+7\times\frac{1}{3}x+2\times\frac{1}{3}\\\\\mathrm{Simplify}\:6x-21+7\times\frac{1}{3}x+2\times\frac{1}{3}:\\\\\quad \frac{25x+2}{3}-21$
