Work: Find the solution of equation （337.26+5X）/(73+X) = 4.7 .
Question type: Equation
Solution:Original question:
| ( | 16863 50 | + | 5 | X | ) | ÷ | ( | 73 | + | X | ) | = | 47 10 |
| Multiply both sides of the equation by: | ( | 73 | + | X | ) |
| ( | 16863 50 | + | 5 | X | ) | = | 47 10 | ( | 73 | + | X | ) |
16863 50 | + | 5 | X | = | 47 10 | ( | 73 | + | X | ) |
16863 50 | + | 5 | X | = | 47 10 | × | 73 | + | 47 10 | X |
16863 50 | + | 5 | X | = | 3431 10 | + | 47 10 | X |
Transposition :
| 5 | X | − | 47 10 | X | = | 3431 10 | − | 16863 50 |
Combine the items on the left of the equation:
3 10 | X | = | 3431 10 | − | 16863 50 |
Combine the items on the right of the equation:
3 10 | X | = | 146 25 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 146 25 | ÷ | 3 10 |
| = | 146 25 | × | 10 3 |
| = | 146 5 | × | 2 3 |
We obtained :
| X | = | 292 15 |
Convert the result to decimal form :
| X | = | 19.466667 |
