Question

Solve for t.

−3t≥39




t≥−13


t≤13

t≥13

t≤−13

Answer 1

One solution was found :  t ≤ -13 (Last answer choice)

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
