What the expresion 6X means
The expression 6x consists of two components: the number 6 and the variable x. In mathematics, when a number is placed directly in front of a variable, it indicates multiplication. So, when you see 6x, it means that you need to multiply 6 by the value of x.
For example, if x = 2, then 6x would be 6 multiplied by 2, resulting in 12. Similarly, if x = -3, then 6x would be 6 multiplied by -3, which gives -18.
In general, the value of 6x depends on the specific value assigned to x. By substituting different values for x, you can determine the result of the expression 6x.
