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 a two step equation with a variable that equals 23?
A two-step equation with a variable that equals 23 could be (2x + 5 = 23). To solve for (x), first subtract 5 from both sides to get (2x = 18), and then divide by 2 to find (x = 9). Thus, the solution satisfies the original equation.
What is a sentence with one or more variables?
well, an equation with one variable is a one step equation and an equation with more than 2 variables is a multi-step equation
16 is 49 percent of what number?
To find the answer to this you will need to create a proportion with one variable. Then cross multiply and finally solve a one-step equation. Set it up like this:49/100 = 16/NThen cross multiply:16 x 100 = 49 x N1600 = 49NThen solve the one-step equation to find your answer.Hope this helps.
