Work: Find the solution of equation （937*4.88+5*X）/（937+X） = 4.9 .
Question type: Equation
Solution:Original question:
| ( | 937 | × | 122 25 | + | 5 | X | ) | ÷ | ( | 937 | + | X | ) | = | 49 10 |
| Multiply both sides of the equation by: | ( | 937 | + | X | ) |
| ( | 937 | × | 122 25 | + | 5 | X | ) | = | 49 10 | ( | 937 | + | X | ) |
| 937 | × | 122 25 | + | 5 | X | = | 49 10 | ( | 937 | + | X | ) |
| 937 | × | 122 25 | + | 5 | X | = | 49 10 | × | 937 | + | 49 10 | X |
114314 25 | + | 5 | X | = | 45913 10 | + | 49 10 | X |
Transposition :
| 5 | X | − | 49 10 | X | = | 45913 10 | − | 114314 25 |
Combine the items on the left of the equation:
1 10 | X | = | 45913 10 | − | 114314 25 |
Combine the items on the right of the equation:
1 10 | X | = | 937 50 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 937 50 | ÷ | 1 10 |
| = | 937 50 | × | 10 |
| = | 937 5 | × | 1 |
We obtained :
| X | = | 937 5 |
Convert the result to decimal form :
| X | = | 187.4 |
