[ 1/1 Equation]
Work: Find the solution of equation 1.11÷(X-18.89) = 3.7 .
Question type: Equation
Solution:Original question:
111 100 | ÷ | ( | X | − | 1889 100 | ) | = | 37 10 |
| Multiply both sides of the equation by: | ( | X | − | 1889 100 | ) |
111 100 | = | 37 10 | ( | X | − | 1889 100 | ) |
111 100 | = | 37 10 | X | − | 37 10 | × | 1889 100 |
111 100 | = | 37 10 | X | − | 69893 1000 |
Transposition :
| - | 37 10 | X | = | - | 69893 1000 | − | 111 100 |
Combine the items on the right of the equation:
| - | 37 10 | X | = | - | 71003 1000 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
71003 1000 | = | 37 10 | X |
If the left side of the equation is equal to the right side, then the right side must also be equal to the left side, that is :
37 10 | X | = | 71003 1000 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 71003 1000 | ÷ | 37 10 |
| = | 71003 1000 | × | 10 37 |
| = | 1919 100 | × | 1 |
We obtained :
| X | = | 1919 100 |
Convert the result to decimal form :
| X | = | 19.19 |
