Answer:
8x - 8z.
Step-by-step explanation:
Let's first rearrange 6x-3y-z+2x+3y-7z where all the x's are together, all y's together, and all z's are together:
6x +2x + 3y - 3y - z - 7z.
First we combine like terms.
6x + 2x ⇒ 8x
3y - 3y ⇒ 0
z - 7z ⇒ -8z.
Since the y's result in 0, we do not include them.
Therefore, our answer is 8x - 8z.

Plug that into your calculator and you'll get the answer
We know that
1 Kg is equals to--------------> 1000 g
so
X Kg------------------------> 300 g
X=300/1000------> x=0.30 Kg
if 2 Kg cost--------------> <span>£7.20
0.30 Kg-------------> X
X=0.30*7.20/2------> x=1.08
the answer is
</span>£1.08
