Question

1) 2/3(x+9)-2=1/6х
2) -6=-2-(4+9х)
3)1,2(5-4х)=6(0,8х+1)

Answer 1

$1) \frac{2}{3}(x+9)-2=\frac{1}{6}x\\\frac{2}{3}x+6-2=\frac{1}{6}x\\\frac{2}{3}x+4=\frac{1}{6}x\\4x+24=x\\4x-x=-24\\3x=-24\\x=-8\\2) -6=-2-(4+9x)\\-6=-2-4-9x\\-6=-6-9x\\0=-9x\\-9x=0\\x=0\\3)1,2(5-4x)=6(0,8x+1)\\6-4,8x=4,8x+6\\-4,8x=4,8x\\-4,8x-4,8x=0\\-9,6x=0\\x=0$
