We can use the following formula to create an expression that means “seven fewer than the product of two and a number x,” which reads as follows:2x – 7
The outcome of multiplying two and a number x together is represented by this formula; then, seven is deducted from the product. In this case, the unnamed number that we are referring to is denoted by the letter x.
Let’s try a value in place of x to observe how the behaviour of this expression changes. For instance, if the value of x is 5, then:
2x – 7 = 2(5) (5) – 7 = 10 – 7 = 3
Because of this, “seven less than the product of two and a number x” is equal to 3 when x is equal to 5.
In a broad sense, we may use the statement “seven less than the product of two and a number x” to represent “two less than the product of a number x” for any value of x.
