x + y = 3 ..... (i)
2x + 5y = 10 ..... (ii)
 
Try to eliminate any of the variables 'x' or 'y' 
 
Let us try to eliminate 'x' 
 
We multiply the first equation by '2' and get
2x + 2y = 6 ..... (iii)
 
We now equate this with eqn (ii)
 
2x + 5y=10 ..... (ii)
2x + 2y = 6 ..... (iii)
 
What should we do here to eliminate 'x'
Lets do (ii) - (iii), we get
3y = 4
y = 4/3
 
Substitute the value of 'y' in any of the eqn to get 'x'
Try and let us know.
