Math Equation Writer
To solve your equation using the Equation Solver, type in your equation like x+4=5. The solver will then show you the steps to help you learn how to solve it on your own. Solving Equations Video Lesson. Khan Academy Video: Solving Simple Equations; Need more problem types? Sep 30, 2019 1. To make equation authoring easier, the equation editor is in math mode by default, so it isn't necessary to add math mode commands to your equations. If the preview is empty or displays an error, check your equation to make sure it’s correct. If an equation is by itself on a line of text, the equation centers based on the equals sign. We can subtract 17 from both sides of the equation to find the value of x. Answer: x = 51, so Jeanne needs $51 to buy the game. In the problem above, x is a variable. The symbols 17 + x = 68 form an algebraic equation. Let's look at some examples of writing algebraic equations. Example 1: Write each sentence as an algebraic equation.

What is an Equation?
An equation says that two things are equal. It will have an equals sign '=' like this:
| x | + | 2 | = | 6 |
That equations says: what is on the left (x + 2) is equal to what is on the right (6)
So an equation is like a statement 'this equals that'
(Note: this equation has the solution x=4, read how to solve equations.
What is a Formula?
A formula is a fact or rule that uses mathematical symbols.
It will usually have:
- an equals sign (=)
- two or more variables (x, y, etc) that stand in for values we don't know yet
It shows us how things are related to each other.
Example: The formula for finding the volume of a box is:
V = lwh
V stands for volume, l for length, w for width, and h for height.
When l=10, w=4, and h=5, then:
V = 10 × 4 × 5 = 200
These are all equations, but only some are formulas:
| x = 2y - 7 | Formula (relating x and y) |
| a2 + b2 = c2 | Formula (relating a, b and c) |
| x/2 + 7 = 0 | Not a Formula (just an equation) |
Without the Equals
Sometimes a formula is written without the '=':
Example: The formula for the volume of a box is:
lwh
But in a way the '=' is still there, because we can write V = lwh if we want to.
Subject of a Formula
The 'subject' of a formula is the single variable (usually on the left of the '=') that everything else is equal to.
Math Formula Writer
Example: in the formula
s = ut + ½ at2
's' is the subject of the formula
Changing the Subject
A very powerful thing that Algebra can do is to 'rearrange' a formula so that another variable is the subject.
Example: Rearrange the volume of a box formula (V = lwh) so that the width is the subject
So if we want a box with a volume of 12, a length of 2, and a height of 2, we can calculate its width:
