Work: Find the solution of equation （8972+51.44+X）*3.5% = 4X .
Question type: Equation
Solution:Original question:
| ( | 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 |
Transposition :
7 200 | X | − | 4 | X | = | - | 789551 2500 |
Combine the items on the left of the equation:
| - | 793 200 | X | = | - | 789551 2500 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
789551 2500 | = | 793 200 | X |
If the left side of the equation is equal to the right side, then the right side must also be equal to the left side, that is :
793 200 | X | = | 789551 2500 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 789551 2500 | ÷ | 793 200 |
| = | 789551 2500 | × | 200 793 |
| = | 789551 25 | × | 2 793 |
We obtained :
| X | = | 1579102 19825 |
Convert the result to decimal form :
| X | = | 79.652055 |
