Work: Find the solution of equation (x+367)/(x+367+130)-0.78 = 0 .
Question type: Equation
Solution:Original question:
| ( | x | + | 367 | ) | ÷ | ( | x | + | 367 | + | 130 | ) | − | 39 50 | = | 0 |
| Multiply both sides of the equation by: | ( | x | + | 367 | + | 130 | ) |
| ( | x | + | 367 | ) | − | 39 50 | ( | x | + | 367 | + | 130 | ) | = | 0 |
| x | + | 367 | − | 39 50 | ( | x | + | 367 | + | 130 | ) | = | 0 |
| x | + | 367 | − | 39 50 | x | − | 39 50 | × | 367 | − | 39 50 | × | 130 | = | 0 |
| x | + | 367 | − | 39 50 | x | − | 14313 50 | − | 507 5 | = | 0 |
11 50 | x | − | 1033 50 | = | 0 |
Transposition :
11 50 | x | = | 0 | + | 1033 50 |
Combine the items on the right of the equation:
11 50 | x | = | 1033 50 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 1033 50 | ÷ | 11 50 |
| = | 1033 50 | × | 50 11 |
| = | 1033 | × | 1 11 |
We obtained :
| x | = | 1033 11 |
Convert the result to decimal form :
| x | = | 93.909091 |
