- What is equation? Define equation.
Equations are mathematical statements that show that two quantities are equal. They typically contain an equal sign (=) and one or more variables. Equations are used to express relationships between quantities and to solve problems in various fields of science, engineering, and mathematics.
Example equations include:
To solve an equation, we want to determine the value of the variable(s) that make the equation true.
There are different techniques to solve equations, but some common steps include:
1. Simplify both sides of the equation by combining like terms and using the order of operations if necessary.
2. Isolate the variable on one side of the equation by undoing any operations that were performed on it.
- For example, if the variable is multiplied by a number, divide both sides of the equation by that number. If the variable is added to a number, subtract that number from both sides of the equation.
3. Check the solution by plugging it back into the original equation to see if it makes the equation true.
