Work: Find the solution of equation （1860×49.95%＋x）÷（1860＋x） = 51% .
Question type: Equation
Solution:Original question:
| ( | 1860 | × | 999 2000 | + | x | ) | ÷ | ( | 1860 | + | x | ) | = | 51 100 |
| Multiply both sides of the equation by: | ( | 1860 | + | x | ) |
| ( | 1860 | × | 999 2000 | + | x | ) | = | 51 100 | ( | 1860 | + | x | ) |
| 1860 | × | 999 2000 | + | x | = | 51 100 | ( | 1860 | + | x | ) |
| 1860 | × | 999 2000 | + | x | = | 51 100 | × | 1860 | + | 51 100 | x |
92907 100 | + | x | = | 4743 5 | + | 51 100 | x |
Transposition :
| x | − | 51 100 | x | = | 4743 5 | − | 92907 100 |
Combine the items on the left of the equation:
49 100 | x | = | 4743 5 | − | 92907 100 |
Combine the items on the right of the equation:
49 100 | x | = | 1953 100 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 1953 100 | ÷ | 49 100 |
| = | 1953 100 | × | 100 49 |
| = | 279 | × | 1 7 |
We obtained :
| x | = | 279 7 |
Convert the result to decimal form :
| x | = | 39.857143 |
