20.004х-2.04х + 2.045 = 17.964х+2.045
если х=101, то 17.964х+ 2.045 = 17.964 • 101 + 2.045 = 1.814.364 + 2.045 = 1.816.409
если х=1000, то 17.964х+ 2.045 = 17.964 • 1000 + 2.045= 17.964000+2.045=20.009000 = 20.009
если х = 0.001, то 17.964х+ 2.045 = 17.964 • 0.001 + 2.045 = 0.017964 + 2.045 = 2.062964
270 000:100*23=6210
6210:4=1552,5
1) 4.5*0.12=0.54
2) 0.81:2.7=0.3
3)0.54+0.3=0.84
4)0.84+0.69=1.53
