plz help!!!solving graph of simultaneous equations!
Heya!
I need help with a ques in maths.....i gotta submit it by 2moro so plz sum1 help me ASAP!!!!
The ques is-
on a single co-ordinate diagram on graph paper, draw the two lines with equations: 2x+y=5 and x-2y=0.

Plz...... help is needed urgently!!!!!!!

If you re-arrange the two equation to make $y$ the subject, it may be easier to plot.

$2x+ y = 5 \rightarrow y=5-2x$
$x-2y=0 \rightarrow y=\frac{x}{2}$

Plot both lines and the point at which they intersect is the solution of the simultaneous equation.

I'm not entirely certain, but I think you are asking for help with learning how to graph linear equations. If so, try here.
