Subtraction Equations: Learn
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 6000 - 4000 = 2000.
One of the terms in an equation may not be know and needs to be determined. Often this unknown term is represented by a letter such as x. (e.g. x - 4000 = 2000).
The solution of an equation is finding the value of the unknown x. To find the value of x we can use the additive equation property which says: The two sides of an equation remain equal if the same number is added to each side.
Check the answer by substituting (120000) for x in the original equation. The answer is correct if the expressions on each side of the equals sign have the same value.
120000 - 50000 = 70000
70000 = 70000 (Correct!)
