(Х-56)-24=17 (х-27)+35=81 478-(256+х)=143 659-(345-х)=427 791-(х-298)=683

Question

(Х-56)-24=17
(х-27)+35=81
478-(256+х)=143
659-(345-х)=427
791-(х-298)=683

Answer 1

1.х-56=24-17
х-56=7
х=56+7
х=63
2.х-27=81-35
х-27=46
х=46+27
х=73
3.256+х=478-143
256+х=335
х=335-256
х=79
4.345-х=659-427
345-х=232
х=345-235
х=110
