this question is to be done by done by the method of family of lines.

so,by this method-(x+y+1)+lambda(2x-3y-1)=0

now x=--2/5 and y=--3/5 are the solutions of the equation x+y+1 =0 and 2x-3y=1.

so,put the values of x and y in the above equation which i have written in the form of lambda.

thus,you will get the value of lambda and so you can get a general equation which passes through the given two lines.
