Let's look at and example: 4x + 8x = 48.
Since there is two of the same variable on the same side, we can add them together, as they are the same. So 8 + 4 = 12.
So it looks like this: 12x = 48
Now in order to work out the answer, we have to isolate the x on one side of the equation. The easiest way to do this is not to move the variable, but to move the number attached to it. In this case, it is the 12. In any case, if a number is attached to a variable, it means that the number attached, is meant to be multiplied by the variable.
12 multiplied by x = 48
Since we are moving the 12, we have to make it's sign opposite, since it is multiplying by the variable, to make it opposite we have to make it 12 dividing by.
x = 48 divided by 12.
48/12 = 4
x = 4.

How do you solve algebra equations?
-- You select an operation. -- You apply the same operation to each side of the equation. -- You keep doing both steps until the equation says (the variable) = (the value of the variable)
What is the basic rules to solve equations?
The basic rules to solve equations are to isolate the variable on one side of the equation by performing the same operation on both sides. This includes adding or subtracting the same value, multiplying or dividing by the same value, and applying exponent or logarithm rules if necessary. The goal is to simplify the equation until the variable is alone on one side and the solution can be determined.
What does it mean to solve a formula for a variable that appears on both sides?
It means that you manipulate the equation in such a way that the variable appears only on one side, by itself.
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.
Can you solve an integer equation by adding the same number to each side?
NO!
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.

How do you solve a linear eqution when there are two letter on the same side?
You cannot solve a single linear equation with two variables. At best you can express one variable in terms of the other.
What is the basic rules to solve equations?
The basic rules to solve equations are to isolate the variable on one side of the equation by performing the same operation on both sides. This includes adding or subtracting the same value, multiplying or dividing by the same value, and applying exponent or logarithm rules if necessary. The goal is to simplify the equation until the variable is alone on one side and the solution can be determined.
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.
what is a 2-step equation ( example please..)?
A two-step equation is an equation that requires two steps to solve We must eliminate any constant that is on the same side as the variable first To solve, use the inverse operations to isolate the variable by itself Remember whatever you do to one side, you must do to the other
What must be done get a variable alone on one side of an equation or inequality in order to solve the equation or inequality the answeranswer has eighteen letters with s being the second?
isolate the variable
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
What does it mean to solve a formula for a variable that appears on both sides?
It means that you manipulate the equation in such a way that the variable appears only on one side, by itself.
How do you solve an equation with a variable on each side?
It's not always to 'solve' as it is to 'simplify' EX: 15a + 3b = 45c simplifies to 5a + b = 15c
Which is the best way to solve the equation?
That depends on the equation. In general, you'll try to isolate the variable, by using operations (on both sides of the equation) that get rid of anything other than the variable, on the side the variable is on.
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.
