I think this is what you're asking for.
3x=9 can be moved to be x=9/3
For a slope/intercept example:
3x-6y=-1 Subtract the 3x
-6y=-3x-1 Divide the negative 6 on y
y=1/2x+1/6 And there, (y=1/2x+1/6) is equal to (3x-6y=-1)

It is an expression with a variable, x.It is an expression with a variable, x.It is an expression with a variable, x.It is an expression with a variable, x.
A variable is a single letter that represents a number. For example x is a variable.An algebraic expression can contain variables, numbers, mathematical symbols, etcetera. An example of an algebraic expression is 3x+12.
If you are talking about math wise then an example of a variable would be any letter in the alphabet. For example in the expression "x-3m" m and x are variables.
It means to replace an expression by another one that is equivalent, but simpler. For example: 3x + 5x can be written as: 8x because of the distributive property.
