Реши уравнения.
48*х+568=1000. 425:х+432=437. 980-360:х=890
948-х:3=586. 2 000:х-40=60. 327-20*х=267

Answer 1

48*х+568=1000
48*х=1000-568
48*х=432
х=432/48
х=9
48*9+568=1000

425/х+432=437
425/х=437-432
425/х=5
х=425/5
х=85
425/85=432=437

980-360/х=890
360/х=980-890
360/х=90
х=360/90
х=4
980-360/4=890

948-х/3=586
х/3=948-586
х/3=362
х=362*3
х=1086
948-1086/3=586

2000/х-40=60
2000/х=60+40
2000/х=100
х=2000/100
х=20
2000/20-40=60

327-20*х=267
20*х=327-267
20*х=60
х=60/20
х=3
327-20*3=267
