Solve the equation :
A) (5x - 4)/2 = (0.5x + 1)/3,
B) 1 –[(x - 3)/5] = ( -3x + 3)/3,
C) (x + 1)/3 – (2x + 5)/2 = -3,
D) [3.(x - 1)]/2 + [2(x + 2)]/4 = (3x + 4.5)/5  Choose one
A) 1, - 3/4, 5/4, 1	B) 1, - 3/4, 5/4, 2	C) 3, - 3/4, 5/4, 1	D) 1, - 3/4, 5/4, 4	E) None
Solution:   1, - 3/4, 5/4, 1) (5x - 4)/2 – (0.5x + 1)/3 &lt;=&gt;   3(5x - 4) = 2(0.5x + 1) &lt;=&gt;   15x - 12 = x + 2 &lt;=&gt;   15x – x = 12 + 2=
