## Question

### Solution

Correct option is

23x + 23y = 11

Equation of any line passing through the intersection of the given lines is

(3x – 4y + 1) + λ(5x + y – 1) = 0  but given     x-intercept = y-intercept  (λ ≠ 1 âˆµ if λ = 1 then line (i) pass through origin)   Substituting the value of λ in (i), we get required equation is

23x + 23y = 11.
