The first one would be correct!
You can solve simultaneously to find the intersection of the lines. Or use the substitution method,
I used the substitution method where I made X the subject in the first method so I got X = -2 +y
use this x to replace it in the second equation
y= 2(-2 + y ) +10
therfore y = 2
to find x coordinate, substitute y in any equation to get x = - 4
so the points of intersection is (-4, 2)
Hope this helped! :)
1/2, I divided 2.50 by 1.50 and ended up getting 1/2.
About 6.5 I believe, I looked it up and a gross was a total of 144 of something, also known as a dozen dozen.
I don’t really know I’m guessing Sorry A 4
