(x, y) → (X, 2X + Y)
3x + 5y  30 = 0
3(X) + 5 (2X + Y)  30 = 0
3X + 10X+ 5Y  30 = 0
13X + 5Y  30 = 0
Now transferred equation 13X + 5Y  30 = 0

x' = x
y'=2x+y=2x'+y >y=y'2x'
replace x,y into 3x + 5y 30 = 0 > 3x'+5(y'2x')30=0 or 7x'+5y'30=0
or
7x5y+30=0

That line is y = 6 – (3/5)x
A point on that line is therefore [x, 6 – (3/5)x]
In the transformation x →x, but,
y→ (2x + y) = 2x + 6 – (3/5)x = (7/5)x + 6
A point on the new line is therefore [x, (7/5)x + 6]
The equation of the new line is y = (7/5)x + 6, or,
5y – 7x – 30 = 0
