Equation

An equation is a mathematical statement in which the expression on the left side of the equal to sign is equal to the expression on the right side.

In an equation the equal to sign indicates that expressions on both sides of the equal to sign are equal to each other. 

For example an equation is shown in the image below.

The left side expression of the equation is 4 + 6

4 + 6 = 10

The right side expression of the equation is 5 x 2

5 x 2 = 10

An example of an equation with an unknown value is given below.

4 x 3 = 6 x ?

In this equation the left side is equal to 4 x 3 

The right side is 6 times the unknown value represented with a question mark.

For the equation to be correct, the unknown value should be such that both the sides are equal.

The left side is equal to 4 x 3

4 x 3 = 12

The right side should also be equal to 12 so that the equation is correctly balanced.

12 = 6 x ?
12 = 6 x 2 

The unknown value should be equal to 2 so that the right side will also be equal to 12.

4 x 3 = 6 x 2

2) 10 x 4 = 8 x ?

An equation is given with an unknown value.

In this equation the left side is equal to 10 x 4 

The right side is 8 times the unknown value represented with a question mark.

The unknown value needs to be calculated.

The left side is equal to 10 x 4

10 x 4 = 40

The right side should also be equal to 40 so that the equation is correctly balanced.

40 = 8 x ?

40 = 8 x 5 

The unknown value should be equal to 5 so that the right side will also be equal to 40.

10 x 4 = 8 x 5
