[ 1/1 Equation]
Work: Find the solution of equation 5000（1+X） = 7200 .
Question type: Equation
Solution:Original question:
| 5000 | ( | 1 | + | X | ) | = | 7200 |
| Left side of the equation = | 5000 | × | 1 | + | 5000 | X |
| = | 5000 | + | 5000 | X |
| 5000 | + | 5000 | X | = | 7200 |
Transposition :
| 5000 | X | = | 7200 | − | 5000 |
Combine the items on the right of the equation:
| 5000 | X | = | 2200 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 2200 | ÷ | 5000 |
| = | 2200 | × | 1 5000 |
| = | 11 | × | 1 25 |
We obtained :
| X | = | 11 25 |
Convert the result to decimal form :
| X | = | 0.44 |
