9 less than the product of a number and -4 is 35 <-- This should clue you into making an expression
The product of a number and -4 means that there's a variable multiplied by -4 or -4x.
"9 less than" means that 9 is being subtracted from this -4x.
Combine these two things and the fact that this expression "is 35" and you have an equation you can now solve for:
-4x- 9 = 35
-4x=44
x=-11
As a check, plug in -11 for the "a number" part of the original question and see if it makes sense:
9 less than the product of a number and -4 is 35
9 less than the product of -11 and -4 is 35.
44-9 = 35
