y = 4x + 6
X+6. Variable (x)
the letter in 2x+6. The variable is the x.
It would be: 6/x whereas x is the unknown variable
To write the expression "4 more than 6 times a number," you would start by writing the mathematical operation for "6 times a number," which is 6x. Then, you would add 4 to this result to get the final expression. Therefore, the expression can be written as 6x + 4.
y = 4x + 6

X+6. Variable (x)
A mathematical expression in its' most simplistic form, merely assigns a value to a variable. Don't confuse an expression with an equation. An equation requires a solution. An expression cannot be "solved". It only allows you to determine the value of a variable. This is the expression in words "x is equal to 3" (X is the variable which is equal to the constant number 3) This is the expression in numbers "x=3" The expression in words "y is equal to 6" (Y is the variable which is equal to the constant number 6) The expression in numbers is "y=6" I hope you understand now.
6x (x is the variable)
the letter in 2x+6. The variable is the x.
When you see "y times 2," it means you are multiplying the variable y by the number 2. So the expression "y times 2" can be written as 2y. This is a simple algebraic expression where the coefficient of y is 2.
It would be: 6/x whereas x is the unknown variable
To write the expression "4 more than 6 times a number," you would start by writing the mathematical operation for "6 times a number," which is 6x. Then, you would add 4 to this result to get the final expression. Therefore, the expression can be written as 6x + 4.

A constant is a number which is fixed in an question. On the other hand, a variable is a number which can change. In your expression, 6 + axb, you have 1 constant (6), and 3 variables (a,x, and b). Hope this helps :)
