4x - 3y = 8 .......... 1
18x - 3y = 29........... 2
- + -
__________
-14x = -21
x= 21/14
x = 3/2
substitute x value in eqn 1
4 (3/2) - 3y = 8
6 - 3y = 8
-3y = 8-6
y = - 2/3
18x - 3y = 29........... 2
- + -

4x-3y=8........(1)
18x-3y=29....(2)
subtract (1) from (2)
18x-3y=29
(-) 4x-3y=8
- + -
--------------
14x=21
then x=3/2
substitute this in eq. (1)
4(3/2)-3y=8
y= -2/3
