Question

24+[5x(24+9xc):3+2]x9=942

Answer 1

24+[5×(24+9×c)÷3+2]×9=942
[5×(24+9c)÷3+2]×9=942-24
[5×(24+9c)÷3+2]×9=918
5×(24+9c)÷3+2=918÷9
5×(24+9c)÷3+2=102
5×(24+9c)÷3=102-2
5×(24+9c)÷3=100
5×(24+9c)=100×3
5×(24+9c)=300
24+9c=300÷5
24+9c=60
9c=60-24
9c=36
c=36÷9
c=4

Answer 2

[5×(24+9×c)÷3+2]×9=942-24
=918
5×(24+9×c)÷3+2=918÷9
=12
5×(24+9×c)÷3=12-2
5×(24+9×c)÷3=10
(24+9×c)÷3=10÷5
(24+9×c)÷3=2
24+9×c=2×3
=6
9×c=24-6
9×c=18
c=18:9
c=2
