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 12 * 11 = 132.
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 * 11 = 132).
The solution of an equation is finding the value of the unknown x. Use the
division property of equations to find the value of x. The division property
of equations states that the two sides of an equation remain equal if both sides are
divided by the same number
Example:
x * 50 = 1000
x * 50 ÷ 50 = 1000 ÷ 50
x * 1 = 20
x = 20
Check the answer by substituting the answer (20) back into the equation.
20 * 50 = 1000
