GOLDEN RULES SOLVING INEQUALITIES Get rid of the Brackets – with Brackets - in Fraction Form THE GOLDEN RULES of Algebra STILL APPLY GOLDEN RULES What you do to the LHS you do to the RHS Get rid of the Brackets Get Your Equation on to the ONE LINE

SOLVING INEQUALITIES – with Brackets (Get rid of the brackets)

(Add -10 to both sides)

SOLVING INEQUALITIES – with Brackets (Get rid of the brackets) (Tidy up) (x-term only on the LHS)

Now let’s look at Fraction Forms…

SOLVING INEQUALITIES – in Fraction Form Remember: The aim is to get the inequality on ONE LINE. If we multiply both sides by 4, that will sort out the 4 on the bottom line of the inequality. Let’s try it. 1 (It’s all on ONE LINE and SOLVED) What’s missing ?

10 is the Lowest Common Denominator or LCD. How do we get this on ONE LINE? 10 is the Lowest Common Denominator or LCD. 1 2 (It’s all on ONE LINE)

If you can do this one….. 1

What you do to the LHS you do to the RHS GOLDEN RULES The rules for Solving an Inequality are IDENTICAL to the rules for solving an equation with one exception …. If you multiply or divide both sides by a negative number, you must REVERSE the inequality sign
