Work: Find the solution of equation （117928*0.968+x）/（117928+x） = 0.98 .
Question type: Equation
Solution:Original question:
| ( | 117928 | × | 121 125 | + | x | ) | ÷ | ( | 117928 | + | x | ) | = | 49 50 |
| Multiply both sides of the equation by: | ( | 117928 | + | x | ) |
| ( | 117928 | × | 121 125 | + | x | ) | = | 49 50 | ( | 117928 | + | x | ) |
| 117928 | × | 121 125 | + | x | = | 49 50 | ( | 117928 | + | x | ) |
| 117928 | × | 121 125 | + | x | = | 49 50 | × | 117928 | + | 49 50 | x |
14269288 125 | + | x | = | 2889236 25 | + | 49 50 | x |
Transposition :
| x | − | 49 50 | x | = | 2889236 25 | − | 14269288 125 |
Combine the items on the left of the equation:
1 50 | x | = | 2889236 25 | − | 14269288 125 |
Combine the items on the right of the equation:
1 50 | x | = | 176892 125 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 176892 125 | ÷ | 1 50 |
| = | 176892 125 | × | 50 |
| = | 176892 5 | × | 2 |
We obtained :
| x | = | 353784 5 |
Convert the result to decimal form :
| x | = | 70756.8 |
