Solving One-Step Inequalities

Objective: To solve one-step inequalities using properties for inequalities Solving One-Step Inequalities

What are the Properties for Inequalities? Are they the same as for regular equations?

Addition Property for Inequalities X-15<73 X-15+15<73+15 X<88 Add 15 to both sides

Solving One-Step Inequalities Subtraction Property for Inequalities y+15<25 Y+15-15<25-15 y<10 Subtract 15 from both sides

Solving One-Step Inequalities Multiplication Property for Inequalities Multiply both sides by the reciprocal of the coefficient

Solving One-Step Inequalities Division Property for Inequalities Divide both sides by the coefficient of x

Division Property for Inequalities Caution! Dividing by a negative number Notice: Sign CHANGED Same if multiplying?

Multiplication Property for Inequalities Caution! When you multiply by a negative number… …the sign CHANGES YES ! -x > 2 5 (-5 )-x > 2(-5) 1 5 x < -10
