But the answer is:
1) x + y = 4
2) x + y = 13
The equations given are parallel lines wherein they never meet however you extend the lines formed. Just by looking, you can say they are parallel since they have the same slope. Also, the second equation is a translated equation of the first one. The y-intercept of the first is moved from zero to negative 3.
I need to see the drawing
The first ratio is 1:4 so if x is 6 then 6x4 is 24 your answer is 24.
