Why would you want to solve a literal equation for a variable when you could simply plug in known values and then solve the resulting linear equation?

if you solve by plugging in the known values ahead of time you won't have a general formula for the variable in the literal equation. Therefor if the known values change, you would have to start all over again, making each problem more individualized. Once the literal equation is solved for some variable, if the known values change all you have to do is plug in those new numbers to your literal equation, and out pops your answer

Can a linear expression have a squared variable?
No, if there is a sqaured variable, the equation is not linear.
Can a linear equation have a variable to the first power?
Any variable in a linear equation is to the first power.The exponent is normally not written.
Why is the exponent of a variable a determining factor in whether an equation is linear?
Because that is how a linear equation is defined!
Wha is a linear equation?
A linear equation is when each term in the algebraic equation is either a constant or the product has a single variable and a constant.
What relationship does a linear graph shows?
A linear graph shows a linear equation in which the value of one variable depends on the value of the other variable.
How does solving a literal equation differ from solving a linear equation?
Because linear equations are based on algebra equal to each other whereas literal equations are based on solving for one variable.

Can a linear expression have a squared variable?
No, if there is a sqaured variable, the equation is not linear.
What is an equation that is not true for any value of a variable?
linear equation in one variable
What are the zeros of a linear equation?
A linear equation can have only one zero and that is the value of the variable for which the equation is true.
Can a linear equation have a variable to the first power?
Any variable in a linear equation is to the first power.The exponent is normally not written.
Why is the exponent of a variable a determining factor in whether an equation is linear?
Because that is how a linear equation is defined!
Can an equation be linear if there is a variable on the bottom?
x2
Wha is a linear equation?

What relationship does a linear graph shows?
A linear graph shows a linear equation in which the value of one variable depends on the value of the other variable.
Is 6x plus -7 a linear equation?
-1
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.
