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
