Question

How many solutions will the following system of linear equations have?
–2x + 4y = –7
y=-1/2x+5

Answer 1

this is easy

Answer 2

do you know how to do a system of equations?

Answer 3

-2x+7=-4y

Answer 4

1 solution.
It cannot have 2 because they do not curve at all.
It cannot have 0 because they are not parallel.
And it cannot have infinitely many because they are not the same line.

Answer 5

2y=-x+10

Answer 6

x=10-2y
then you put x here---> -2x+7=-4y
and solve it
