Question

Solve for t.

−3t≥39




1.) t≥−13


2.) t≤13

3.) t≥13

4.) t≤−13

Answer 1

One solution was found : t ≤ -13 (number 4)

Pull out like factors :

-3t - 39 = -3 • (t + 13)

Divide both sides by -3

Remember to flip the inequality sign:

Solve Basic Inequality :

Subtract 13 from both sides to get t≤−13
