    Answer:

    t ≥ 5

    Step-by-step explanation:

    I) Find what t needs to be at least, represent this with u:

    5 – 2u = -4

    -2u + 5 = -4 (Simplify by swapping signs and terms for 5 – 2u)

    -2u = -9 (Subtract 5 from both sides)

    2u = 9 (Make both sides positive values)

    u = 4.5 (Divide both sides by 2)

    II) Make an inequality for t:

    Since t needs to be equal to or greater than 4.5, our inequality will be:

    t ≥ 4.5
