I don't know 5 and 7 it's to complicated for me plus I haven't learned how do those kind

6)7/3 (c+3)=1/3-c
7/3c+7=1/3-c
3×7/3c+3×7=3×1/3-3c
7c+3c=1-21
10c=-20
c=-2

\(4.2(1.2b)- \frac{-0.9b}{2} =5.94\)
\(5.04b--0.45b =5.94\)
\(5.04b+0.45b =5.94\)
\(5.49b=5.94\)
\(b = \frac{5.94}{5.49} = 1.08197 (approximately)\)

\(7/3(c+3) = 1/3-c\)
\(\frac{7c}{3} + 7 = \frac{1}{3} - c\)
\(7c+21 = 1 - 3c\)
\(10c+21 = 1\)
\(10c = -20\)
\(c=-2\)

\(\frac{11g}{6} + \frac{9}{2} - \frac{2}{3} -5 =0\) (I interpret 3 3/2 as 3 times 3/2, although this unconventional writing method could be interpret in multiple ways and should be avoided)
\(\frac{11g}{6} + \frac{27}{6} - \frac{4}{6} - \frac{30}{6} =0\)
\(11g+27-4-30=0\)
\(11g-7=0\)
\(11g=7\)
\(g = \frac{7}{11}\)

\(9.1= \frac{2.8(4h-1 )}{4}\)
\(36.4= 11.2h-2.8\)
\(39.2= 11.2h\)
\(h= \frac{39.2}{11.2} =3.5\)
