Work: Find the solution of equation 4700+1500+x+【（4700+x）/21.75*8】 = 30500 .
Question type: Equation
Solution:Original question:
| 4700 | + | 1500 | + | x | + | ( | ( | 4700 | + | x | ) | ÷ | 87 4 | × | 8 | ) | = | 30500 |
| Left side of the equation = | 6200 | + | x | + | ( | ( | 4700 | + | x | ) | ÷ | 87 4 | × | 8 | ) |
| 6200 | + | x | + | ( | ( | 4700 | + | x | ) | ÷ | 87 4 | × | 8 | ) | = | 30500 |
| Left side of the equation = | 6200 | + | x | + | ( | 4700 | + | x | ) | ÷ | 87 4 | × | 8 |
| = | 6200 | + | x | + | ( | 4700 | + | x | ) | × | 32 87 |
| = | 6200 | + | x | + | 4700 | × | 32 87 | + | x | × | 32 87 |
| = | 6200 | + | x | + | 150400 87 | + | x | × | 32 87 |
| = | 689800 87 | + | 119 87 | x |
689800 87 | + | 119 87 | x | = | 30500 |
Transposition :
119 87 | x | = | 30500 | − | 689800 87 |
Combine the items on the right of the equation:
119 87 | x | = | 1963700 87 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 1963700 87 | ÷ | 119 87 |
| = | 1963700 87 | × | 87 119 |
| = | 1963700 | × | 1 119 |
We obtained :
| x | = | 1963700 119 |
Convert the result to decimal form :
| x | = | 16501.680672 |
