Step-by-step explanation:
2x + 3y - 7 = 0 (eqn no. 1)
3x - 2y - 8 = 0 (eqn no. 2)
(equal the value of x or y in both the eqn)
multiplying eqn. no. 1 by 3
= 3(2x + 3y - 7)
= 6x + 9y - 21 (eqn no. 3)
multiplying eqn. no. 2 by 2
= 2(3x - 2y - 8)
= 6x - 4y - 16 (eqn no. 4)
(subtracting eqn no. 3 by eqn no. 4)
(6x + 9y - 21) - (6x - 4y - 16)
= 6x + 9y - 21 - 6x + 4y + 16
= (6x - 6x) + (9y + 4y) + (-21 + 16)
= 13y - 5
13y - 5 = 0
13y = 5
y = 5/13
putting the value of y in eqn no. 1
2x + 3y - 7 = 0
2x + 3(5/13) = 7
2x + 15/13 = 7
26x + 15 = 91
26x = 91 - 15
26x = 76
x = 76/26
x = 38/13
