( | 8972 | + | 1286 25 | + | X | ) | × | 7 200 | = | 4 | X |
Left side of the equation = | 8972 | × | 7 200 | + | 1286 25 | × | 7 200 | + | X | × | 7 200 |
= | 15701 50 | + | 4501 2500 | + | X | × | 7 200 |
= | 789551 2500 | + | 7 200 | X |
789551 2500 | + | 7 200 | X | = | 4 | X |
7 200 | X | − | 4 | X | = | - | 789551 2500 |
- | 793 200 | X | = | - | 789551 2500 |
789551 2500 | = | 793 200 | X |
793 200 | X | = | 789551 2500 |
