Answer:
2
Explanation:
1/2(n-4) - 3 = 3 - (2n+3) Distribute the 1/2 and the -1
1/2n - 2 - 3 = 3 -2n -3 Combine like terms
1/2n -5 = -2n Add 2n to both sides
2 1/2n - 5 = 0 Add 5 to both sides
2 1/2n = 5
n = 5 Multiply both sides by


n =


n = 2
Check:
1/2(n-4) -3 = 3 - (2n + 3)
1/2 (2 -4) - 3 = 3 - (2(2) + 3)
1/2(-2) - 3 = 3 - (4 + 3)
-1 - 3 = 3 - 7
-4 = -4
