\(4x-12=x+6 \Rightarrow 3x=18 \Rightarrow x=6\)
\(4-6x-12=3-5x \Rightarrow -x=11 \Rightarrow x=-11\)
\(5x+8-8x-14=9 \Rightarrow -3x=15 \Rightarrow x=-5\)
\(2,7+3y=9y-18,9 \Rightarrow 6y=21,6 \Rightarrow y=3,6\)
\(2,4-0,9y=8,8-0,8y \Rightarrow -0,1y=6,4 \Rightarrow y=-64\)
\(\frac{5}{6}\left(\frac13x-\frac15\right)=3x+\frac{10}{3}\) \(\frac{5x}{18}-\frac16=3x+\frac{10}{3}\) \(-\frac{49}{18}x=\frac72 \Rightarrow x=-\frac97\)
