Ответ:
1.) x - 2y = 6
y = x/2 -3
2.) 2x - 4y = 10
y = x/2 - 5/2
As we look at the rearranged equations, we see that their slopes are equal which means they are parallel lines so they do not intersect at one point. There is no solution for this system of equations.

Answer A becouse:
x-=20
y=55
y-35=2(x-10)
y=2x-20+35=40-20+35=55
