Deal with inequalities just like equations, except that you reverse the carats when multiplying or dividing by a negative number.
Is there a typo in the first inequality?
5-(3) < 10(-3)
2 < -30 (That certainly is not true. Think of it in terms of money. Having $2 is not less than owing $30.)
3 < 2x+1 < 9
Subtract 1 from each part.
2 < 2x < 8
Divide each part by 2.
1 < x < 4
Use these principles in the remaining problems.
