X | − | X | × | 13 200 | − | ( | X | + | 10000000 | ) | × | 3 10000 | = | 10000000 |
Left side of the equation = | 187 200 | X | − | ( | X | + | 10000000 | ) | × | 3 10000 |
187 200 | X | − | ( | X | + | 10000000 | ) | × | 3 10000 | = | 10000000 |
Left side of the equation = | 187 200 | X | − | X | × | 3 10000 | − | 10000000 | × | 3 10000 |
= | 187 200 | X | − | X | × | 3 10000 | − | 3000 |
= | 9347 10000 | X | − | 3000 |
9347 10000 | X | − | 3000 | = | 10000000 |
9347 10000 | X | = | 10000000 | + | 3000 |
9347 10000 | X | = | 10003000 |
X | = | 10003000 | ÷ | 9347 10000 |
= | 10003000 | × | 10000 9347 |
X | = | 100030000000 9347 |
