6.1 Solving Inequalities
4
What is an inequality? What are the inequality signs? An inequality is a statement that shows how two expressions compare, using greater than or less than symbols.
5
Steps for Solving an Inequality 1)Distribute 2)Combine like terms 3)Move the variable to one side 4)Undo addition or subtraction 5)Undo multiplication or division (if mult. or div. by a neg. change sign)
6
Examples Solve. 1)2x + 1 > 13 - 1 -1 2x > 12 2 X > 6 2) 7 – 2t > 21 -7 - 7 -2t > 14 -2 t < -7
