YOU CAN SOLVE FOR A VARIABLE IN AN EQUATION, BUT NOT AN EXPRESSION.. FOR EXAMPLE: RIGHT WAY: 4u+6=26
-6 -6
So you are left with 4u=20
now you divide the 4u by 4 because you want to do the
opposite of multiplying. also, you divide the 20 by 4.
So... u=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.
Solve xyz for the variable y?
solve x=yz for the variable y
How do you solve an or problem if a variable is unrestricted in sign?
Solve the problem using the + sign for the variable. Then solve the problem using the - sign for the variable. Report your answer as the answer that you got using + or the answer that you got using -.
What is the math term VEST?
variable equation solve it test it
How do you solve for the variables?
Yes, that is what you are normally required to solve for.
How do you find the value of a variable of a proportional ratio?
Cross multiply then solve for the 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.
How do you know whether a relation is a function?
Use the definition of a function. If, for any value of one variable, there is only a single possible value of the second variable, then the second variable is a function of the first variable. The second variable is often called the "dependent variable". If you can solve an equation explicitly for the dependent variable, then it is a function. If you can NOT solve it for a variable, it may or may not be a function - it turns out that some equations are hard or impossible to solve explicitly for one of the variables.
How do you solve algebraic expresions?
You solve algebraic expressions by getting the variable by itself.
Can you solve for the value of a variable in an expression?
Yes
How do you solve dependent variable questions?
