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.
