Hi,

I have solved it simultaneously but have trouble understanding how to draw the graph. If someone could draw it from or aid me in how to do it. It would be a pleasure.

ok it is there now....

if you have a statement

"5x + 2y = 3.6"

you can rearrange it into the form

y = 1.8 - 2.5x

which is the equation of a straight line....

It's against forum rules to post solutions, but surely you have plotted graphs of the form y = mx + c or alternatively ax + by = c? You just need to draw a couple of straight lines representing the info you're given and find their intersection

Just use the form y = mx + c. If you rearrange the two equations you have into that form, you should be able to just find the intersection by equating the two lines, and therefore draw the graph.
