2,3x-5
Online, “*” is used to indicate multiplication to avoid confusion with “x” as an unknown.
Assuming the comma has the same meaning as a period in the USA:
2.3 * -5 = -11.5
It appears that you have provided an expression: 2,3x-5. However, I noticed a comma between the numbers 2 and 3. If you intended to multiply 2 and 3, the correct expression would be written as 2 * 3x - 5.
To simplify this expression, let's start by using the distributive property to multiply 3x by 2:
2 * 3x = 6x
Now, our expression becomes:
6x - 5
This is the simplified form of the expression 2 * 3x - 5.
