55\times 10\times 5=10-y
Multiply both sides of the equation by 5.
550\times 5=10-y
Multiply 55 and 10 to get 550.
2750=10-y
Multiply 550 and 5 to get 2750.
10-y=2750
Swap sides so that all variable terms are on the left hand side.
-y=2750-10
Subtract 10 from both sides.
-y=2740
Subtract 10 from 2750 to get 2740.
y=-2740
Multiply both sides by -1.
