Can someone write for me a review writing for any product?

The hoverboard is a great advance in technology and great way to get around. However it has some flaws. I know this was a few years ago but hoverborads used to blow up in people’s faces. It was really dangerous.  They are supposed to have changed and the technology is supposed to be more advanced and not blow up. So aside from that I’d give the hoverboard 4 stars.

Explanation:

x=4, y=4

step-by-step explanation:

y=2x-4;

x+2y=12

we can use substitution since the first equation is solved for y

where ever you see y in the second equation, replace it with 2x-4

x + 2(2x-4) = 12

distribute the 2

x+4x-8 = 12

combine like terms

5x-8=12

add 8 to each side

5x-8+8=12+8

5x=20

divide by 5

5x/5 = 20/5

x =4

we still need to solve for y

y = 2x-4

we know x =4

y = 2(4) -4

y = 8-4

y=4

yeah it is i have the dark knight
