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.
