In substitution method u have to find the value of any variable in terms of second variable and then substitute the value in second equation.

For example equations are:

2x+ 3y= 5.......(i)

and, x+ y=5........(ii)

from (ii)equation:

y= 5-x.....(iii)

substituting value in (i):

2x+ 3(5-x)= 5

2x+ 15 -3x= 5

x= 10

from (iii):

y=-5
