TWO STEP EQUATIONS
Remember: Equations are balanced on the equals sign, so what is done to one side of the equation must also be done to the other side of the equation. We will look at equations that require two steps to determine the solution.
INEQUALITIES
An inequality is a math sentence that expresses quantities that are greater than, less than, greater than or equal, or less than or equal to a given number or mathematical expression.
The rules for solving equations are similar to the rules for solving inequalities. To solve addition and subtraction inequalities, keep both sides of the inequality sign in balance by undoing what’s been done to the unknown. Isolate the unknown on one side of the inequality.
To solve multiplication and division inequalities, keep both sides of the inequality sign in balance by undoing what’s been done to the unknown. Isolate the unknown on one side of the inequality.
***Something New***
When multiplying or dividing an inequality by a number with a negative sign, “reverse the direction” of the inequality sign.
