It is to make the variable the subject of the equation.
The answer depends on the equation!
A) Divide both sides of the equation by 4.
As it appears, there is no equation but an algebraic term.
No, actually the dependent variable changes. The independent variable does not change, or can "stand alone".
"Solve an equation" means "find out, for which values of the variable or variables is the equation true".
In an equation b or any other letters usually denotes the unknown variable.
When you solve a one-variable equation, your goal is to isolate the variable.To isolate the variable means to make it be alone on one side of the equals sign.In the equation shown here, you can isolate the variable by subtracting 9 from both sides of the equation and simplifying
isolate the variable
that is pi.there isnt really a variable there it just looks like n
Divide both sides of the equation by 15
direct variation, and in the equation y=kx the k ca NOT equal 0.
