To represent the given problem, first start with the beginning statement. Since it is stated that the product, meaning that there is multiplication, and less than meaning subtraction.
Product of 4 less than a number and nine is 15 can be represented as:
4 (x-9) =15
In order to find the value of x, simply multiply four in the equation inside the parenthesis.
4x -36 = 15
Transpose 36 to the other side of the equation, and divide both sides by 4 in order to find the value of x.
4x = 15 + 36
4x = 51
4x/4 = 51 / 4
x = 12.75
