Решите уравнение: 1.(x+3,8)-5,4=72,85 2.(x-23,58)+37,6=150,78 3.10,36+(x-56,051)=120,309 4.35,56-(x+12,07)=18,49

1) х+3,8-5,4=72,85
х-1.6=72.85
х=72.85+1.6
х=74.45
2)х-23.58+37.6=150.78
x+14.02=150.78
x=136.76
3) 10.36+x-56.051=120.309
x-45.691=120.309
x=166
4)35,56-x+12.07=18.49
47.63-x=18.49
x=29.14
