Solve each equation by multiplying or dividing each side by the same number. **If you are multiplying or dividing by a negative number, switch the inequality sign to go the other way in your answer.​
** If the signs are different the answer is negative. If the signs are the same(neg & neg.) the answer is positive. Use an open circle to graph < or >. Use a closed circle to graph ≤ or ≥ Example: 3x < 45 Divide both sides by 3 to solve. 3x ​
< ​
45 3 3 x < 15 Ex: ­3x < 45 Divide both sides by ­3 ​
­3x ​
< ​
45 ­3 ­3 Since both sides were divided by a negative number, the inequality sign was switched to go the other way. x > ­15 Ex: ​
x ​
> ­14 This is a divide problem, so multiply both sides by 6. 6 ​
x ​
(6) > ­14(6) Do not switch the sign, we multiplied by a positive number. 6 x > ­84 Ex: ​
x ≤ 4 Multiply both sides by ­5 ­5 ​
x ​
(­5) ≤ 4 (­5) Since we are multiplying by ­5, switch the inequality sign in the ­5 answer. x ≥ ­20
