Which equation can be used to represent "three minus the difference of a number and one equals one-half of the difference of three times the same number and four”?
A
(1 – n) – 3 = (4 – 3n)
B
3 – (1 – n) = (4 – 3n)C
(n – 1) – 3 = (3n – 4)D
3 – (n – 1) = (3n – 4)2

Which equation has no solution?
A
4(x + 3) + 2x = 6(x + 2)B
5 + 2(3 + 2x) = x + 3(x + 1)C
5(x + 3) + x = 4(x + 3) + 3D
4 + 6(2 + x) = 2(3x + 8)4
