Answer 1

$\displaystyle 1)(4x+0,5)*6-(x+3)=2x-2\\24x+3-x-3=2x-2\\23x=2x-2\\23x-2x=-2\\21x=-2\\\\x=-\frac{2}{21}\\ \\2)\frac{6x-1}{2}=\frac{5-2x}{3}\\ \\3(6x-1)=2(5-2x)\\ 18x-3=10-4x\\18x+4x=10+3\\22x=13\\\\x=\frac{13}{22}\\ \\3)\frac{x+8}{0,2}=\frac{5x-4}{0,5}\\ \\\frac{x+8}{\frac{1}{5} }=\frac{5x-4}{\frac{1}{2} }\\ \\(x+8)*5=(5x-4)*2\\ 5x+40=10x-8\\ 5x-10x=-8-40\\-5x=-48\\\\x=\frac{48}{5}=9\frac{3}{5}=9,6$
