    Answer:

    x = 7/5 or 1.4.

    Step-by-step explanation:

    1/2(n-1) – 3 = 3 – (2n + 3)

    1/2 n – 1/2 – 3 = 3 – (2n + 3)  Distribute the negative over the parentheses:

    1/2 n – 1/2 – 3 =3 – 2n – 3      Bring terms in n to the left and numbers right:

    1/2 n + 2n = 3 + 1/2 + 3 – 3

    5/2 n = 7/2

    n = 7/2 * 2/5

    n = 14/10

    n = 7/5 or 1.4.
