Answer
8x + 13y - 29 = 0 …………… (1)
12x - 7y - 17 = 0 …………… (2)
Multiply 3 in the first equation and 2 in the second equation, then subtract both equations.
⇒ (8x + 13y = 29) x 3
(12x - 7y = 17) x 2
⇒ y =
⇒ y = 1
Substituting the value of y in equation (1), we get:
⇒ 8x + 13 1 = 29
⇒ 8x + 13 = 29
⇒ 8x = 29 - 13
⇒ 8x = 16
⇒ x =
⇒ x = 2
Hence, the value of x = 2 and y = 1.
