the negative variable would mean the opposite of. so therefore if u have -x= 4 ur answer would be the opposite of four which is negative 4.

What do you do when you have a negative variable?
When you have a negative variable in an equation that you are trying to solve for, you multiply each side of the equation by -1. If it is an inequality such as <, you would flip the sign to > and vice versa.

To solve would be to rewrite the equation in terms of the variable in the equation. For example, solve: 3x-2=7. You would solve for the variable x; e.g. 3x=9 and x=3. To evaluate, you would be given an equation with a variable or variables. You would need to be given a value for the variable(s) to substitute into the equation. For example evaluate the equation for x=3; equation is x2+1. Substitute 3 in for x; or 32+1=10. To simplify, reduce the equation to its simplest form. This will involve operations such as: factoring, adding, subtracting, dividing, canceling terms, and so forth. For example simplify the equation: 3x3/9x2. The 3/9 is simplified to 1/3 and x3/x2 is simplified to x. So the original equation simplified is: 1/3 times x or (1/3)x or x/3.Which is the right answer for most of you who does not know.
Can you solve for a variable in an expression?
No, you can only simplify an expression. To solve for a variable, it must be in an 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.

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.

What number when substituded for the variable in an equation makes the equation true?
you have to solve the actual equation in order to answer this about your variable
Can you solve for a variable in an expression?
No, you can only simplify an expression. To solve for a variable, it must be in an equation.
Can you solve for a variable in an expression or equation?
you can only solve for one in an equation so it can equal something
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.
How do you solve an equation with 1 variable?
carefully
What does SOLVE stand for in math?
"Solve an equation" means "find out, for which values of the variable or variables is the equation true".
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.
How do you solve an equation with a variable that is a fraction?
You solve the equation the same way as you would any other equation. Whether the variable is a fraction or otherwise will only become clear once you solve the equation. In other words, you don't initially KNOW whether the solution will be a fraction or not.
