[ 1/1 Equation]
Work: Find the solution of equation （29+x）/(37+x) = 0.808 .
Question type: Equation
Solution:Original question:
| ( | 29 | + | x | ) | ÷ | ( | 37 | + | x | ) | = | 101 125 |
| Multiply both sides of the equation by: | ( | 37 | + | x | ) |
| ( | 29 | + | x | ) | = | 101 125 | ( | 37 | + | x | ) |
| 29 | + | x | = | 101 125 | ( | 37 | + | x | ) |
| 29 | + | x | = | 101 125 | × | 37 | + | 101 125 | x |
| 29 | + | x | = | 3737 125 | + | 101 125 | x |
Transposition :
| x | − | 101 125 | x | = | 3737 125 | − | 29 |
Combine the items on the left of the equation:
24 125 | x | = | 3737 125 | − | 29 |
Combine the items on the right of the equation:
24 125 | x | = | 112 125 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 112 125 | ÷ | 24 125 |
| = | 112 125 | × | 125 24 |
| = | 14 | × | 1 3 |
We obtained :
| x | = | 14 3 |
Convert the result to decimal form :
| x | = | 4.666667 |
