An equation is a mathematical statement such that the expression on the left
side of the equals sign (=) has the same value as the expression on the right side.
An example of an equation is 72 ÷ 8 = 9.

One of the terms in an equation may not be known and needs to be determined.
The unknown term may be represented by a letter such as x. (e.g. x ÷ 8 = 9).

The solution of an equation is finding the value of the unknown x. Use the
multiplication property of equations to find the value of x. The multiplication
property property of equations states that the two sides of an equation remain equal if both sides are
multiplied by the same number

Example:

x ÷ 5 = 2

x ÷ 5 * 5 = 2 * 5

x ÷ 1 = 10

x = 10

Check the answer by substituting the answer (10) back into the equation.

10 ÷ 5 = 2
