Question

How many solutions will the following system of linear equations have?

–2x + 4y = –7
y=-1/2x+5

Answer 1

look, make equation 1 equals : y=(2x-7)/4
and then plug in Y from the second equation to find value of X,
then plug the value of XX in any equation to find Y

Answer 2

value of xx?

Answer 3

What does the / mean in the first equation once you've rearranged it?

Answer 4

sorry its X
and / means division\[y=\frac{ 2x-7 }{ 4 }\]

Answer 5

Ohhh I see.

Answer 6

good
