X | ÷ | 5 | + | 51 | − | X | ÷ | 12 | = | 51 | − | X | ÷ | 4 | + | X | ÷ | 12 |
Left side of the equation = | 7 60 | X | + | 51 |
7 60 | X | + | 51 | = | 51 | − | X | ÷ | 4 | + | X | ÷ | 12 |
Right side of the equation = | 51 | − | 1 6 | X |
7 60 | X | + | 51 | = | 51 | − | 1 6 | X |
7 60 | X | + | 1 6 | X | = | 51 | − | 51 |
17 60 | X | = | 51 | − | 51 |
17 60 | X | = | 0 |
X | = | 0 | ÷ | 17 60 |
= | 0 | × | 60 17 |
X | = | 0 |
