Question

Решение уравнений 210+х=150+240

Answer 1

210+x=150+240
210+x=390
x=390-210
x=180

Answer 2

240:(х+3)-5=7 345*(250*125)*(8*400)=34500000000
240:(х+3)=7+5
240:(х+3)=12
х+3=240:12
х+3=20х=20-3
х=17


16*(11-х:8)=64
11-х:8=64:16
11-х:8=4
х:8=11-4
х:8=7
х=7*8
х=56

300-5400:(24+х)=210
5400:(24+х)=300-210
5400:(24+х)=90
24+х=60
х=60-24
х=36

Answer 3

210+х=390
х=390-210
х=180
Ответ: 180
