Answer:

x-y-5=0

Step-by-step explanation:

x+2y-4=0.....(1)

3x+y+3=0.....(2)

solve 1 and 2nd that is rhe intersection point of both line, it will be (-2,3)

let the equation of required line is given

 \frac{x}{a}  +  \frac{y}{b} = 1 \\  ...(3)

where a and b are the intercept on x and y axis respectively.

a =  - b(given)

line is passing throught (-2,3) so put in equation 3

 \frac{ - 2}{a}  +  \frac{3}{ - a}  = 1 \\  \frac{ - 2}{a}  -  \frac{3}{a}  = 1 \\ a = 5 \\ and \: solve \: b \\ b = 5

so equation of line is

x/-5+y/5=1

-x/5+y/5=1

-x+y=5

x - y - 5 = 0
