A)
Equation Solution \[3m+6=0\] \[m=-5\]
B)
Equation Solution \[5r+10={\scriptstyle{}^{1}/{}_{2}}~~\] \[r=9/2\]
C)
Equation Solution \[\frac{3x}{2}-3=6\] \[x=6\]
D)
Equation Solution \[0.7x-1.3=0\] \[x=2.1~\]
Correct Answer: C
Solution :
(c) \[\frac{3x}{2}-3=6\] \[\Rightarrow \,\,\frac{3x}{2}=9\Rightarrow x=\frac{9\times 2}{3}=\frac{18}{3}=6\]
