Since we have to solve this system graphically, we'll have to draw both lines.
To draw a line, simply build a little tables with two x,y values: for the first line we have

So, you can draw the points (0,3) and (1,2), connect them, and you'll have the graph of the line 
For the second line we have

So, you can draw the points (0,5) and (1,6), connect them, and you'll have the graph of the line 
Finally, we have to check where the two lines cross. If your drawing is accurate enough, you'll see that the point you're looking for is (-1, 4)
Answer:
8 suits
Step-by-step explanation:
Divide 30 m by 3
m , or 30 ÷ 3.75 , then
30 ÷ 3.75 = 8
Then 8 suits can be made from 30 m of cloth
Perimeter = 18 = 8 + 2x + 3x
10 = 5x
x = 2
So the sides are 8, 4 and 6
