Question

X-2y=4 x-2y=5 how many solutions does these equations have

Answer 1

No solutions

Explanation:

Rewrite x-2y=4 x-2y=5 in column form:

x-2y=4

x-2y=5

Because both equations have x - 2y on the left and different constants on the right, we know immediately that there is no solution. These two lines are parallel and different; they never cross.
