Given :  x  + 2y - 4  = 0

2x - 3y - 7 = 0

To Find : x and y

Solution:

 x  + 2y - 4  = 0    Eq1

 2x - 3y - 7 = 0    Eq2

2 x Eq1  - Eq2

=> 2( x  + 2y - 4 )  - ( 2x - 3y - 7) = 0

=> 2x + 4y - 8 - 2x + 3y +7 = 0

=> 7y  - 1 = 0

=> y =1/7

3 x Eq1 + 2 x Eq2

=> 3( x  + 2y - 4 )  + 2 (2x - 3y - 7) = 0

=>3x + 6y - 12 + 4x - 6y - 14 = 0

=> 7x  - 26 = 0

=> x = 26/7

x = 26/7  and y =1/7
