[ 1/1 Equation]
Work: Find the solution of equation 100 = 6.672*X/(X+1400) .
Question type: Equation
Solution:Original question:
| 100 | = | 834 125 | X | ÷ | ( | X | + | 1400 | ) |
| Multiply both sides of the equation by: | ( | X | + | 1400 | ) |
| 100 | ( | X | + | 1400 | ) | = | 834 125 | X |
| 100 | X | + | 100 | × | 1400 | = | 834 125 | X |
| 100 | X | + | 140000 | = | 834 125 | X |
Transposition :
| 100 | X | − | 834 125 | X | = | - | 140000 |
Combine the items on the left of the equation:
11666 125 | X | = | - | 140000 |
The coefficient of the unknown number is reduced to 1 :
| X | = | - | 140000 | ÷ | 11666 125 |
| = | - | 140000 | × | 125 11666 |
| = | - | 70000 | × | 125 5833 |
We obtained :
| X | = | - | 8750000 5833 |
Convert the result to decimal form :
| X | = | - 1500.085719 |
