X | ÷ | 131 | − | ( | 100 | − | X | ) | ÷ | 1000 | = | 381 1000 |
Left side of the equation = | 1 131 | X | − | 100 | × | 1 1000 | + | X | × | 1 1000 |
= | 1 131 | X | − | 1 10 | + | X | × | 1 1000 |
= | 1131 131000 | X | − | 1 10 |
1131 131000 | X | − | 1 10 | = | 381 1000 |
1131 131000 | X | = | 381 1000 | + | 1 10 |
1131 131000 | X | = | 481 1000 |
X | = | 481 1000 | ÷ | 1131 131000 |
= | 481 1000 | × | 131000 1131 |
= | 37 | × | 131 87 |
X | = | 4847 87 |
X | = | 55.712644 |
