We can represent this with a variable such as x. So, our complete division equation then will look like: 100 / 4 = x. We have an equals sign and things on both sides of it. One side has the division operator and
Your ultimate goal is to get all of the constants on one side of the equation and all of the variables on the other side of the equation. You can accomplish this by adding or subtracting terms on BOTH sides of the equation. Let's take a look at a few examples. Example 1 - Variable...
A Solution is a value we can put in place of a variable (such as x) that makes the equation true.Example: x − 2 = 4 When we put 6 in place of x we get: 6 − 2 = 4 which is true So x = 6 is a solution. How about other values for x ? For x=5 we get "5−...

There are two sides to an equation, with the left side being equal to the right side. Equations will often involve algebra and contain unknowns (variables) which we often represent with letters such as x or y. We can solve simple equations and more complicated equations to work out the va...
A rational equation contains at least one rational expression where the variable appears in at least one of the denominators. How To: Given a rational equation, solve it. Factor all denominators in the equation. Find and exclude values that set each denominator equal to zero. Find the LCD. ...
Solving an equation is computing the unknown variable still balancing the equation on both sides. Learn the procedures in solving an equation through examples.
If they'd given me the linear equation "x + 3 = 0" to solve, I'd have known exactly how to proceed: I would have subtracted 3 from both sides, getting the variable by itself. I can do the same thing here: x+3<0−3−3x < −3x+3−3x<0−3<−3 Then my hand...
An equation containing terms with a variable in the radicand is called a radical equation. How To: Given a radical equation, solve it. Isolate the radical expression on one side of the equal sign. Put all remaining terms on the other side. If the radical is a square root, then square ...
