# Present as a product y (x + 0.2) -2.7 (x + 0.2) and find its numerical value y = 1607 x = 1.8.

| Let’s start the solution by representing the expression y (x + 0.2) – 2.7 (x + 0.2) as a product. And if we look closely at the expression, we will see that it is the difference between the two products.

Each of the works contains the same parenthesis. Let’s take it out of the bracket as a common factor:

y * (x + 0.2) – 2.7 * (x + 0.2) = (x + 0.2) (y – 2.7).

Now let’s calculate the value of the expression for a given value of the variables y = 16.7 and x = 1.8;

(1.8 + 0.2) (16.7 – 2.7) = 2 * 14 = 28.

Answer: 28.
