Question

Реши уравнение
（х+3,8）-5,4-=72,85
（х-23,58）+37,6=150,78
10.36+（х-56.051）=
120.309
35.56-（х+12.07）=18.49

Answer 1

х+ 3,8 = 72,85+5,4
х+3,8. = 78;25
х=78,25-3,8
х=74,45

х-23,58=150,78-37,6
х-23:58=113,18
х=113,18+23,58
х=136,76

10,36+(х+56,051)=120,309
х+56,051=120,309-10,36
х+56,051=130,669
х=130,669-56,051
х=74,618

35,56-(х+12,07)=18,49
х+12,07=35,56-18,49
х+12,07=17,07
х=17,07+12,07
х=5
