How do you solve log sub 9 parenthesis a over 27 closed parenthesis equals x minus 2?
Your equation has two variables in it ... 'a' and 'x'. So the solution is a four-step process: 1). Get another independent equation that relates the same two variables. 2). Solve one of the equations for one of the variables. 3). Substitute that into the other equation, yielding an equation in a single variable. Solve that one for the single variable. 4). Substitute that value back into the first equation, and solve it for the second variable.
What is y-c equals -2?
It is a linear equation in two unknown variables, y and c. One linear equation in two unknowns cannot be solved, it can only be arranged so that one or the other variable is the subject of the equation. However, that requires you to identify which variable is to be made the subject of the equation.
How is solving a two step equation different from one step equations?
In a two step equation, you need to do another step.
How do you do 2 step equations with two variables?
I don't really know but usually it is done with one variable. If it has two variables there might be two unknown anwers to the equation.
What reduces an equation that has two variables to an equation that has one variable. It is then possible to find the solution for this variable.?
substitution
