If you have an expression with many variables, you can often solve for a different one. One classic example is rate x time = distance.
We use the variable rxt=d
Now this is solved for d, but say you want to solve for t. You divide both sides by r and
t=d/r and it is solved for t.
What else can I help you with?
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 equation with the same variable on both sides?
The variables may have different values.
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
Which is the best way to solve the equation?
That depends on the equation. In general, you'll try to isolate the variable, by using operations (on both sides of the equation) that get rid of anything other than the variable, on the side the variable is on.
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 solve algebraic expresions?
You solve algebraic expressions by getting the variable by itself.
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.
Can you solve for the value of a variable in an expression?
Yes
