Question

Решите уравнения.
168: Х +12= 3*11
(132- Х)+24=144
356 - (у+122)=122

Answer 1

168:х+12=3*11
168:х+12=33
168:х=21
х=168:21
х=8
168:8+12=33
33=33

(132-х)+24=144
(132-х)=144-24
(132-х)=120
х=132-120
х=12
(132-12)+24=144
144=144

356-(у+122)=122
у+122=356-122
у+122=234
у=234-122
у=112
356-(112+122)=122
122=122
