900000 | = | 50000 | ( | 30 | − | X | ) | − | X |
Right side of the equation = | 50000 | × | 30 | − | 50000 | X | − | X |
= | 1500000 | − | 50000 | X | − | X |
= | 1500000 | − | 50001 | X |
900000 | = | 1500000 | − | 50001 | X |
50001 | X | = | 1500000 | − | 900000 |
50001 | X | = | 600000 |
X | = | 600000 | ÷ | 50001 |
= | 600000 | × | 1 50001 |
= | 200000 | × | 1 16667 |
X | = | 200000 16667 |
X | = | 11.99976 |
