Answer:
x = 3, y = 4
Step-by-step explanation:
3x - 5y + 1 = 0
3x - 5y = -1 ................ (1)
x - y + 1 = 0
x - y = -1 .................. (2)
expressing y interms of x in equation 2
x + 1 = y
substituting x - 1 = y in equation 1
3x - 5y = -1
3x - 5( x + 1 ) = -1
3x - 5x + 5 = -1
-2x = -1 - 5
-2x = -6
x = 3
substituting x=3 in equation 1
x - y = -1
(3) - y = -1
3 - y = -1
- y = -1 - 3
- y = -4
y = 4
