Question

A) x+(1200-900)=1500

b) (50*30):y=15

d) c:(1200:2)=3

Answer 1

A) х=1200-900=300
х=1500-300
х=1200
Ответ:1200
б)у=50•30
У=1500
У=1500:15
У=100
Ответ:100
В)с=1200:2
С=600
С=600•3
С=1800
Ответ:1800

Answer 2

А)х+300=1500
х=1500-300
х=1200

b) 1500:у=15
у=1500:15
у=100

d) с:600=3
с=600*3
