Doesn't your textbook provide examples of how to solve simultaneous equations?
 
Darn budget cuts!

Seriously, you can always use substitution, solving for one variable in terms of another and then plugging that into the other equation to solve for the variables.

You can also look at this though a lot of what they speak of is too involved for what you would need. http://en.wikipedia.org/wiki/System_of_linear_equations

Give substitution a shot and then let us know how it goes.
 
its no use :'( i dont even know how to start solving the equation...plz help
 
\(\displaystyle i_1=3-i_2\) so \(\displaystyle 3(3-i_2)+2i_2=7\)

This is not a teaching site. The title says it all: it is a freeHELP site.
You post work. We look at it and try to help.
There are tutoring sites. But most charge a fee.
Our help is free. But we do not do the work for you.
Why won't you post some of your own work?
