Two equal sides of an isosceles triangle...

Two equal sides of an isosceles triangle are given by `7x-y+3=0` and `x+y=3`, and its third side passes through the point `(1,-10)`. Find the equation of the third side.

A

x – 3y – 31 = 0 but not 3x + y + 7 = 0

B

neither 3x + y + 7 = 0 nor x – 3y – 31 = 0

C

3x + y + 7 = 0 or x – 3y – 31 = 0

D

3x + y + 7 = 0 but not x – 3y – 31 = 0
