[ 1/1 Equation]
Work: Find the solution of equation （100+（8-x）+1+0.459）*0.03 = x .
Question type: Equation
Solution:Original question:
| ( | 100 | + | ( | 8 | − | x | ) | + | 1 | + | 459 1000 | ) | × | 3 100 | = | x |
| Left side of the equation = | 100 | × | 3 100 | + | ( | 8 | − | x | ) | × | 3 100 | + | 1 | × | 3 100 | + | 459 1000 | × | 3 100 |
| = | 3 | + | ( | 8 | − | x | ) | × | 3 100 | + | 3 100 | + | 1377 100000 |
| = | 304377 100000 | + | ( | 8 | − | x | ) | × | 3 100 |
| = | 304377 100000 | + | 8 | × | 3 100 | − | x | × | 3 100 |
| = | 304377 100000 | + | 6 25 | − | x | × | 3 100 |
| = | 328377 100000 | − | 3 100 | x |
328377 100000 | − | 3 100 | x | = | x |
Transposition :
| - | 3 100 | x | − | x | = | - | 328377 100000 |
Combine the items on the left of the equation:
| - | 103 100 | x | = | - | 328377 100000 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
328377 100000 | = | 103 100 | 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 :
103 100 | x | = | 328377 100000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 328377 100000 | ÷ | 103 100 |
| = | 328377 100000 | × | 100 103 |
| = | 328377 1000 | × | 1 103 |
We obtained :
| x | = | 328377 103000 |
Convert the result to decimal form :
| x | = | 3.188126 |
