Answer:
Step-by-step explanation:
3x - 7y + 10 = 0 -------------- (i)
y - 2x - 3 = 0
=> y = 2x + 3 ------------- (ii)
Substitute value of y from (ii) in (i)
3x - 7(2x + 3) + 10 = 0
3x - 14x - 21 + 10 = 0
-11x - 11 = 0
- 11x = 11
x = - 1
Substitute value of x in (ii)
y = 2x + 3
= 2(-1) + 3
= 1
Thus x = -1, y = 1.
