Question

X:9=11 x+75=2075 x•8=720 56:x=56 90-x=90

Answer 1

Х:9=11, х=9*11, х=99
х+75=2075, х=2075-75, х=2000
х*8=720, х=720:8, х=90
56:х=56, х=56:56, х=1
90-х=90, х=90-90, х=0

Answer 2

Х:9=11. х+75=2075
х=9*11. х=2075-75
х=99. х=2000

х*8=720. 56:х=56
х=720:8. х=56:56
х=90. х=1

90-х=90
х=90-90
х=0
