☆1 equations
[ 1/1 Equation]
Work: Find the solution of equation (1.001+0.715X)/(X+1) = 0 .
Question type: Equation
Solution:Original question:
| ( | 1001 1000 | + | 143 200 | X | ) | ÷ | ( | X | + | 1 | ) | = | 0 |
| Multiply both sides of the equation by: | ( | X | + | 1 | ) |
| ( | 1001 1000 | + | 143 200 | X | ) | = | 0 |
1001 1000 | + | 143 200 | X | = | 0 |
Transposition :
143 200 | X | = | 0 | − | 1001 1000 |
Combine the items on the right of the equation:
143 200 | X | = | - | 1001 1000 |
The coefficient of the unknown number is reduced to 1 :
| X | = | - | 1001 1000 | ÷ | 143 200 |
| = | - | 1001 1000 | × | 200 143 |
| = | - | 7 5 | × | 1 |
We obtained :
| X | = | - | 7 5 |
Convert the result to decimal form :
| X | = | - 1.4 |
