Work: Find the solution of equation （8962.82+51.44+X）*3.5% = 4X .
Question type: Equation
Solution:Original question:
| ( | 448141 50 | + | 1286 25 | + | X | ) | × | 7 200 | = | 4 | X |
| Left side of the equation = | 448141 50 | × | 7 200 | + | 1286 25 | × | 7 200 | + | X | × | 7 200 |
| = | 3136987 10000 | + | 4501 2500 | + | X | × | 7 200 |
| = | 3154991 10000 | + | 7 200 | X |
3154991 10000 | + | 7 200 | X | = | 4 | X |
Transposition :
7 200 | X | − | 4 | X | = | - | 3154991 10000 |
Combine the items on the left of the equation:
| - | 793 200 | X | = | - | 3154991 10000 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
3154991 10000 | = | 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 | = | 3154991 10000 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 3154991 10000 | ÷ | 793 200 |
| = | 3154991 10000 | × | 200 793 |
| = | 3154991 50 | × | 1 793 |
We obtained :
| X | = | 3154991 39650 |
Convert the result to decimal form :
| X | = | 79.571021 |
