Answer
3x - 5y = -1 …………… (1)
2x - y = -3 …………… (2)
Multiply 2 in the first equation and 3 in the second equation, then subtract both equations.
(3x - 5y = -1) x 2
(2x - y = -3) x 3
⇒ y = -
⇒ y = - 1
Substituting the value of y in equation (1), we get:
⇒ 3x - 5 (-1) = -1
⇒ 3x + 5 = -1
⇒ 3x = -1 - 5
⇒ 3x = -6
⇒ x = -
⇒ y = - 2
Hence, the value of x = -2 and y = -1.
