Question

4 Реши уравнения.
(134 545 - x) + 23 = 98
2 002 + x 5 = 46 022
(x + 52):7 = 700
34 000 + x 1 000 = 76 000​

Answer 1

(134 545-х)+23=98
134 545-х=98-23
134 545-х=75
х=134 545-75
х=134 470

2002+5х=46022
5х=46022-2002
5х=44020
х=44020:5
х=8804

(х+52):7=700
х+52=700*7
х+52=4900
х=4900-52
х=4848

34000+1000х=76000
1000х=76000-34000
1000х=42000
х=42000:1000
х=42
