Unformatted text preview: rue inequality. This means that our solutions will, in most cases, be inequalities themselves. Example 1 Solving the following inequalities. Give both inequality and interval notation forms of the solution. (a) -2 ( m - 3) < 5 ( m + 1) - 12 [Solution] (b) 2 (1 - x ) + 5 £ 3 ( 2 x - 1) [Solution] Solution Solving single linear inequalities follow pretty much the same process for solving linear equations. We will simplify both sides, get all the terms with the variable on one side and the numbers on the other side, and then multiply/divide both sides by the coefficient of the variable to get the solution. The one thing that you’ve got to remember is that if you multiply/divide by a negative number then switch the direction of the inequality. © 2007 Paul Dawkins 124 http://tutorial.math.lamar.edu/terms.aspx College Algebra (a) -2 ( m - 3) < 5 ( m + 1) - 12 There really isn’t much to do here other than follow the process outlined above. -2 ( m - 3) < 5 ( m + 1) - 12 -2m + 6 < 5m + 5 - 12 -7m < -13 13 m> 7 You d...
