30x-210y=150   

Let's solve for x.
30x−210y=150
Step 1: Add 210y to both sides.
30x−210y+210y=150+210y
30x=210y+150
Step 2: Divide both sides by 30.
30x30=210y+15030
x=7y+5:

@aloud 
In solving word problems, whenever we use a variable not defined in the question, we need to define them, including units, before we set up equations.

Let x=number of lawns mowed in 7 days, then
30x-7(210)$\ge$150
30x$\ge$1470+150
30x$\ge$1620
x$\ge$54
So in fact, your answer is correct by setting y=7 days.
