The solution

You have entered [src]
x*y + 48*y = 51/5
$$x y + 48 y = \frac{51}{5}$$
Detail solution
Given the linear equation:
x*y+48*y = (51/5)

Expand brackets in the right part
x*y+48*y = 51/5

Divide both parts of the equation by (48*y + x*y)/x
x = 51/5 / ((48*y + x*y)/x)

We get the answer: x = -48 + 51/(5*y)
The solution of the parametric equation
Given the equation with a parameter:
$$x y + 48 y = \frac{51}{5}$$
