14/5х = -1,44: (-3/7*(-6/10))
х= -1,44: 9/35 : 14/5
х= -1,44*35/9*5/14
х= -1,44*25/18
х= - 1 44/100*25/18
х= - 144/100*25/18
х= - 144/4*1/18= -36*1/18= -2
2) 4,2+х=6,6+2,2
х=8,8-4,2=4,6
3)0,24х=0,08:(-1/3)
х= 2/25:(-1/3):6/25
х= 2/25*25/6*(-3)
х= 1/3*(-3)= -1
4) -12у=1,44:0,06
у=1,44:0,06:(-12)=144:6:(-12)= -2
