What is the term for an equation with more than variable?

An equation with more than one variable is called a multivariate equation.

What does solve the equation mean?

Find values for the variable that satisfy the equation, that is if you replace those values for the variable into the original equation, the equation becomes a true statement.

What is the difference between a algebraic equation and a monomial?

The first is an equation which may contain any powers of the variable - including fractional powers. The second is a single term.

Can you solve a variable with an equation?

When an equation has a variable in it (only one), then there are only certainvalues the variable can have that will make the equation a true statement."Solving" the equation means finding those values for the variable.

What is 306g is equal too 22.5?

Can you solve for a variable in an equation?

Sure. You can always 'solve for' a variable, and if it happens to be the only variable in the equation, than that's how you solve the equation.

Why do you isolate the variable on one side the the equation when solving a linear equation?

Isolating a single variable in terms of the rest of the equation provides a solution to that variable. That is, if you know the equation that equals the variable, then you can figure out its value.

What is is an equation with more than one variable called?

What is the first step to solving for x?

That depends on the specific equation. The general idea is to "isolate" the variable, for example "x", manipulating the equation in such a way that all terms that contain "x" are on the left, and all terms that don't contain it, are on the right.
