x=0

Step-by-step explanation:

-7x - 12 = - 7x + 3(-4 - x)

Open up the parentheses

-7x - 12 = - 7x -12-3x

-7x cancels out on both sides

-12 =-12-3x

-12 cancels out on both sides

$0=-3x\\x=0$

I hope this helps!

Step-by-step explanation:

a) write 2 2/3 as an improper fraction in its simplest form....

$= 2 \frac{2}{3} \\$

$= \frac{2 \times 3 + 2}{ 2} \\$

$= \frac{8}{2} \\$

$= \frac{8 \div 2}{2 \div 2} \\$

$= \frac{4}{1} = 4 \\$

B) Work out 2 2/3 x5 give your anwser as an improper...

$= 2 \frac{2}{3} \times 5 \\$

$= \frac{2 \times 3 + 2}{3} \times 5 \\$

$= \frac{8}{3} \times 5 \\$

$= \frac{40}{3} \\$
