How do you get a variable alone on one side of a equation or inequality is the variable?
alright so our equation is 2x+4=-x+7 so you want to get the variable on one side.
start by adding x to each side because you have a negative x, you get rid of it by adding a positive x. your equation will now look like this 3x+4=7. If at this point you want to solve the equation you would subtract 4 from each side to get the equation 3x=3. Now here comes the tricky part, since 3x is actually x times three, you do the opposite to get rid of the 3 part of 3x. so you would divide 3x by 3 to get x, and in algebra you must do to one side as you do to the other so you would divide 3 by 3 to get 1. so if you did it correctly, your solution should be x=1. that's the best i can word it, best of luck!

How can you get the variable alone on one side of the equation 4c 139?
If you mean: 4c = 139 then divide both sides by 4 and so c = 34.75
What step can be taken to get the variable w alone on one side of the equation 6w 42?
What you have listed is not an equation but I assume you meant 6w = 42. If you divide both sides by 6 you get w = 7.
How do you solve algerbric equation?
The methods vary widely, depending on the type of equation. The general principle is to do the same manipulation on both sides of the equation, trying to isolate the variable (leave the variable alone on one side of the equation). For example, if you have x + 3 = 7 your objective is to have the "x" alone on one side, so you subtract 3 on each side. This results in: x + 3 - 3 = 7 - 3 x + 0 = 4 x = 4 (You don't usually need to write down all these steps; they were included for clarity.)

isolate the variable
What is it called when a when you get a variable alone on one side of an equation or inequality in order to solve the equation or inequality?
each of the four regions created on the coordinate plane by the x- and y-axes.
What is it called when you have to get the variable alone on one side of an equation?
It is to make the variable the subject of the equation.
What do you do when you have a negative variable?
When you have a negative variable in an equation that you are trying to solve for, you multiply each side of the equation by -1. If it is an inequality such as <, you would flip the sign to > and vice versa.
How would you get the variable m alone on one side of the equation 15m equals 45?
Divide both sides of the equation by 15
What is an equation with one or two variables?
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
How do you solve 3n equals 36?
3n=36 Write the equation n=12 Divide each side of the equation by 3 to get the variable alone.
What does isolation of the variable mean?
isolation of the variable means to get the variable on one side of the equation and the integers on the other side
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.
What does isolate mean in math?
To completely isolate the variable, we have to divide both sides of the equation by 6. x = 24 / 6 x = 4 Now, x is all by itself or "isolated". We can read the answer right from the equation. x equals 4. To review, isolating the variable means getting every term containing the variable on one side of the equationfound on google...
How do you solve compound inequalities?
For example, let's start off with: 9x + 3 > 3x + 2First, get rid of the smallest 6x + 3 > 2variable, 3x, by subtracting3x from 9x.Then, subtract 3 from both 6x > -1sides to isolate thevariable.Now divide each side by x > -1/66 to get x alone to solvethe inequality.Summary: Subtract one coefficient from another coefficient to get one coefficient on one side of the equation. Subtract one constant on one side of the equation from the other so that the coefficient is completely alone on its side of the equation. Finally, if their is a constant attached to the variable, which the pair is called a coefficient, divide whatever the constant of the variable is on both sides of the equation to get the variable alone to solve the equation.
How do you solve for the indicated variable?
Algebraically manipulate the equation until you have the indicated variable on one side of the equation and all of the other factors on the other side.
