Algebra 1: Lesson 022

Equations with Decimals
Integer Solutions

Lesson Description

Students learn that if one or more decimals appear in an equation, the first step is to get rid of the decimals by multiplying both sides of the equation by the appropriate power of 10. For example, if the equation reads x + .7 = .9x - 3, since both decimals are taken to the tenths place, the decimals can be removed by multiplying both sides of the equation by 10, to get 10x + 7 = 9x - 30. Note that all solutions in this lesson are integers.
