Answer 1

Ответ:

96:4+x=257

24+x=257

x=257-24

x=233

y-95:5=800

y-19=800

y=800+19

y=819

84:6*b=140

14*b=140

b=10

147:7*b=210

21:b=210

b=10

Answer 2

Ответ:

1.96:4+х=257

96:4=24

24+х=257

х=257-24

х=233

24+233=257

2.у-95:5=800

95:5=19

у-19=800

у=19+800

у=819

819-19=800

3.84:6*b=140

84:6=14

14*b=140

b=140:14

b=10

14*10=140

4.147:7*b=210

147:7=21

21*b=210

b=210:21

b=10

21*10=210
