    Answer:

    -2.1

    Step-by-step explanation:

    We have an equation and the question is asking us to look for x.

    To solve, we must isolate x and get it on its own.

    2.5(x + 4) = 4.75

    Distribute the 2.5 to get rid of the parenthesis :

    (2.5(x) + 4(2.5)) = 4.75

    2.5x + 10 = 4.75

    Subtract ten from both sides :

    2.5x = -5.25

    Divide 2.5 by both sides to get x alone :

    x = -2.1
