18\times 5=16+18+24+x+27
Multiply both sides by 5.
90=16+18+24+x+27
Multiply 18 and 5 to get 90.
90=34+24+x+27
Add 16 and 18 to get 34.
90=58+x+27
Add 34 and 24 to get 58.
90=85+x
Add 58 and 27 to get 85.
85+x=90
Swap sides so that all variable terms are on the left hand side.
x=90-85
Subtract 85 from both sides.
x=5
Subtract 85 from 90 to get 5.
