take 2 any equations like 2x+3y=11(1) and 3x+5y=12(2) .....from (1) u can find that x=(113y)/2...substitute this x value in eqn. (2) and solve...u'll get the value of y

i understabd substituting the final value, i just have to get it first. i dont know how to solve 4x + y = 6

what i have done is i got the value of y from 2nd equation and substituted in first so by substituting y in 1st equation u will get equation in x terms from u will get x value and substitute x value in any equation and get y

5x + 6 + 4x = 21 1x + 6 = 21 1x = 15 x = 15 ?

move the 6 and 4x and the operation changes? thought i forgot something 5x + 4x  6 = 21 1x  6 = 21 1x = 26 x = 26
