X | − | 2 100 | X | − | 239 10 | − | 4 100 | X | − | 12 5 | − | 53 1000 | X | = | 87 |
Left side of the equation = | 887 1000 | X | − | 263 10 |
887 1000 | X | − | 263 10 | = | 87 |
887 1000 | X | = | 87 | + | 263 10 |
887 1000 | X | = | 1133 10 |
X | = | 1133 10 | ÷ | 887 1000 |
= | 1133 10 | × | 1000 887 |
= | 1133 | × | 100 887 |
X | = | 113300 887 |
X | = | 127.733935 |
