An equation is a condition on a variable. A variable is something that can vary. It assumes different numerical values; its value is not fixed. These are usually denoted by letters of the english alphabet, such as x, y, z, l, m, n, p, etc
What is Equation
An equation is a condition on a variable. The condition is that two expressions should have equal value. Note at least one of the two expressions must contain the variable.
An equation remains the same when the expressions on the left and on the right are interchanged. This property is often useful in solving equations
Properties of an Equation
- add the same number to both sides,the balance is undisturbed.
- subtract the same number from both sides,the balance is undisturbed.
- multiply by the same number to both sides, the balance is undisturbed.
- divide by the same number both its sides, the balance is undisturbed.
Transposing of an Equation
Transposing means moving to the other side. It has the same effect as adding the same number to (or subtracting the same number from) both sides of the equation.When we transpose a number from one side of the equation to the other side, we change its sign.
Note :- A Simple Equation remains the same when the expression in the left and right are interchanged completely.
Applications of Simple Equations
We know how to convert statements in everyday language into simple equations. To solve the problems we have to solve these equations by the usual method.
- Suppose unknown variable as x
- Form an equations with conditions given in question using x in it
- Solve equations (using properties of equations / Transposing )
- Value of x is solution
