The constant is the number; the variable is the letter.
9
Simple,its just like this: 6x+1+7-3 =6x+8-3 =6x+5
It is a linear expression in one variable, x. It is not an equation and so cannot be solved. It can be simplified to -6x-27.
-6x-66=66 First, add 66 to both sides to isolate the variable -6x=132 Then, divide by -6 and x=-22
4 sin(6x) cos(6x) is already a function of a single variable. The variable is ' x '.
(6x-6)
The constant is the number; the variable is the letter.
6x (x is the variable)

Numbers that have the same variable or powers of a variable, such as 2x and 6x.
Simple,its just like this: 6x+1+7-3 =6x+8-3 =6x+5
It is a linear expression in one variable, x. It is not an equation and so cannot be solved. It can be simplified to -6x-27.
-6x-66=66 First, add 66 to both sides to isolate the variable -6x=132 Then, divide by -6 and x=-22
16x = 6x + 100 (subtract 6x from both sides) 16x - 6x = 6x +100 - 6x (Therefore) 10x = 100 (Divide both sides by 10) 10x/10 = 100/10 (Therefore) x = 10 Answer: Value of x is 10
A variable expression for the product of 6 and 3 can be written as ( 6 \times 3 ) or simply ( 18 ). If you want to introduce a variable, you could represent it as ( 6x ) where ( x ) is equal to 3. Thus, the variable expression can also be written as ( 6 \cdot 3 ) or ( 6x ) with ( x = 3 ).
the number with the variable. For example, in 6x, the coefficient is 6.
