Let say the question stated that it also parallel to the y-axis;

2x+5y-8=0
2x+5y=8 .............. (P1)

x-3y+4=0
x=3y-4 ................. (P2)

replace (P2) into (P1);

2x+5y=8
2(3y-4)+5y=8
6y-8+5y=8
11y=8+8
11y=16
y=16/11

x=3y-4
x=3(16/11) -4
x=48/11 -4
x=48/11 -44/11
x=4/11

the coordinate of the intersection point of two lines is (4/11,16/11)

then, draw a straight line across the point of 4/11 on the x-axis so that the line will be parallel to the y-axis
