[ 1/1 Equation]
Work: Find the solution of equation 35/（10*（x+3.8）/(13.8+x)+35） = 2.73/12 .
Question type: Equation
Solution:Original question:
| 35 | ÷ | ( | 10 | ( | x | + | 19 5 | ) | ÷ | ( | 69 5 | + | x | ) | + | 35 | ) | = | 273 100 | ÷ | 12 |
| Multiply both sides of the equation by: | ( | 10 | ( | x | + | 19 5 | ) | ÷ | ( | 69 5 | + | x | ) | + | 35 | ) |
| 35 | = | 273 100 | ÷ | 12 | × | ( | 10 | ( | x | + | 19 5 | ) | ÷ | ( | 69 5 | + | x | ) | + | 35 | ) |
| 35 | = | 273 100 | ÷ | 12 | × | 10 | ( | x | + | 19 5 | ) | ÷ | ( | 69 5 | + | x | ) | + | 273 100 | ÷ | 12 | × | 35 |
| 35 | = | 91 40 | ( | x | + | 19 5 | ) | ÷ | ( | 69 5 | + | x | ) | + | 637 80 |
| Multiply both sides of the equation by: | ( | 69 5 | + | x | ) |
| 35 | ( | 69 5 | + | x | ) | = | 91 40 | ( | x | + | 19 5 | ) | + | 637 80 | ( | 69 5 | + | x | ) |
| 35 | × | 69 5 | + | 35 | x | = | 91 40 | ( | x | + | 19 5 | ) | + | 637 80 | ( | 69 5 | + | x | ) |
| 35 | × | 69 5 | + | 35 | x | = | 91 40 | x | + | 91 40 | × | 19 5 | + | 637 80 | ( | 69 5 | + | x | ) |
| 483 | + | 35 | x | = | 91 40 | x | + | 1729 200 | + | 637 80 | ( | 69 5 | + | x | ) |
| 483 | + | 35 | x | = | 91 40 | x | + | 1729 200 | + | 637 80 | × | 69 5 | + | 637 80 | x |
| 483 | + | 35 | x | = | 91 40 | x | + | 1729 200 | + | 43953 400 | + | 637 80 | x |
| 483 | + | 35 | x | = | 819 80 | x | + | 47411 400 |
Transposition :
| 35 | x | − | 819 80 | x | = | 47411 400 | − | 483 |
Combine the items on the left of the equation:
1981 80 | x | = | 47411 400 | − | 483 |
Combine the items on the right of the equation:
1981 80 | x | = | - | 145789 400 |
The coefficient of the unknown number is reduced to 1 :
| x | = | - | 145789 400 | ÷ | 1981 80 |
| = | - | 145789 400 | × | 80 1981 |
| = | - | 20827 5 | × | 1 283 |
We obtained :
| x | = | - | 20827 1415 |
Convert the result to decimal form :
| x | = | - 14.718728 |
