When Do You Flip The Sign In An Inequality Equation
Olivia Luz
You flip the inequality sign when you are dividing or multiplying both sides by a negative you also flip the inequality sign when you swap the answers on both sides the other time you flip the.
For example if you have 2x 8 and divide both sides by 2 you end up with. An inequality is a comparison statement that is similar to an equation but uses an inequality symbol of or instead of an equal symbol. Now it s a rule of thumb to flip the inequality when you multiply both sides by a negative number but you don t even need to use multiplication to see why this is the case. Flip the inequality sign when you multiply or divide both sides of an inequality by a negative number.
Multiplying and dividing inequalities by negative numbers. When you multiply or divide both sides of the inequality by a negative number you can flip the sign. 9 x 3 3 x 9 2 the inequality sign changes when multiplying or dividing by a negative number so that the solution is true. You also often need to flip the inequality sign when solving inequalities with absolute values.
This principle does not apply to equations because in an equation you have only an equal sign so the answer can only equal or not equal. To solve you need to get all the x es on the same side of the inequality. No only flip when multiplying or dividing by a negative no matter what the other numbers are. 3 4 a 21.
