3x times x is the same as 3x times 1x seeing that x has the same value its basically 3times 1 but don't forget the x so 3x
Another way is to take out the x from 3 and 1 x(3*1) = x(3) =3x

3 is the coefficient of x and 3x means 3 times x which on its own is not an equation because there is no equality sign .
"x" stands for any unknown or variable quantity; 3x means 3 times this quantity.
This is only half of an equation. If -x^2 + 3x +2y = 0, then x^2 -3x = 2y and y = (x^2-3x)/2 Solving for x is the inverse, but difficult without a second equation.
It is an equation: 3x+11=32 and the value of x is 7
x*3=8 Multiply x by 3 to get 3x. 3x=8 Divide each term in the equation by 3. (3x)/(3)=(8)/(3) Simplify the left-hand side of the equation by canceling the common terms. x=(8)/(3)
