Work: Find the solution of equation （5a+4.7755*2062）/（a+2062） = 4.84 .
Question type: Equation
Solution:Original question:
| ( | 5 | a | + | 9551 2000 | × | 2062 | ) | ÷ | ( | a | + | 2062 | ) | = | 121 25 |
| Multiply both sides of the equation by: | ( | a | + | 2062 | ) |
| ( | 5 | a | + | 9551 2000 | × | 2062 | ) | = | 121 25 | ( | a | + | 2062 | ) |
| 5 | a | + | 9551 2000 | × | 2062 | = | 121 25 | ( | a | + | 2062 | ) |
| 5 | a | + | 9551 2000 | × | 2062 | = | 121 25 | a | + | 121 25 | × | 2062 |
| 5 | a | + | 9847081 1000 | = | 121 25 | a | + | 249502 25 |
Transposition :
| 5 | a | − | 121 25 | a | = | 249502 25 | − | 9847081 1000 |
Combine the items on the left of the equation:
4 25 | a | = | 249502 25 | − | 9847081 1000 |
Combine the items on the right of the equation:
4 25 | a | = | 132999 1000 |
The coefficient of the unknown number is reduced to 1 :
| a | = | 132999 1000 | ÷ | 4 25 |
| = | 132999 1000 | × | 25 4 |
| = | 132999 40 | × | 1 4 |
We obtained :
| a | = | 132999 160 |
Convert the result to decimal form :
| a | = | 831.24375 |
