12 = -3/2u
12 (2u) = -3
24u = -3
u = -3 / 24
u = (-3/3) / (24/3)
u = -1 / 8
u = -0.125

12 = -3/2u
12 * 2u = -3
24u = -3
u = -1/8

(i) if it is 12 = -3/(2u)
then multiply by -2/3 to both side,
we get u= - 1/8
(ii) if it is 12 = (-3/2)u
then by mutiplying -2/3 to both side,
we get u = -8
bye...

Step-by-step
12= -3/2u
24=-3/u
24/-3=1/u
-8=1/u
u= -1/8

i) 12(2u) = -3
ii) 24u = -3
iii) u = -3/24
iv) u = -0.125
PS: how will you reward the best answer? There's only one answer (except for those who said "8" ... whoops). The answer is -0.125 (or -1/8). Many people would HOPEFULLY come up with that. Cheers

12 = -3/2u
12*-2/3 = -3/2*-2/3u (multiply both sides by -2/3)
-8 = u

u=-1/8

multiply both sides by -2/3: u = -8
