The variable in 14x is x.

It means that you multiply 2 by any given number (h) and then multiply by 5. h is the variable. A variable is anunknown number. So if h is 3, then you replace it with h so 2 times 3 is 6 times 5 is 30.

"Wat" is the variable.

If a variable has possible values -2 6 and 17 then this variable is an Integer.

Generally speaking, a letter in algebra refers to a variable, that is, it is a placeholder for any specific value that can be used in that equation.In algebra syntax, a number next to a variable, or a variable next to another variable, with no explicit arithmetic symbol between them, mean to multiply the two values.So:2aMeans to multiply the variable value of "a" by two.In your question:2aball values should be multiplied. So, the result would be 2 times the variable value of "a" times the variable value of "b".
