Work: Find the solution of equation 4100+1500+x+【（4100+x）/21.75*8】 = 7000 .
Question type: Equation
Solution:Original question:
| 4100 | + | 1500 | + | x | + | ( | ( | 4100 | + | x | ) | ÷ | 87 4 | × | 8 | ) | = | 7000 |
| Left side of the equation = | 5600 | + | x | + | ( | ( | 4100 | + | x | ) | ÷ | 87 4 | × | 8 | ) |
| 5600 | + | x | + | ( | ( | 4100 | + | x | ) | ÷ | 87 4 | × | 8 | ) | = | 7000 |
| Left side of the equation = | 5600 | + | x | + | ( | 4100 | + | x | ) | ÷ | 87 4 | × | 8 |
| = | 5600 | + | x | + | ( | 4100 | + | x | ) | × | 32 87 |
| = | 5600 | + | x | + | 4100 | × | 32 87 | + | x | × | 32 87 |
| = | 5600 | + | x | + | 131200 87 | + | x | × | 32 87 |
| = | 618400 87 | + | 119 87 | x |
618400 87 | + | 119 87 | x | = | 7000 |
Transposition :
119 87 | x | = | 7000 | - | 618400 87 |
Combine the items on the right of the equation:
119 87 | x | = | - | 9400 87 |
The coefficient of the unknown number is reduced to 1 :
| x | = | - | 9400 87 | ÷ | 119 87 |
| = | - | 9400 87 | × | 87 119 |
| = | - | 9400 | × | 1 119 |
Get the solution of the equation :
| x | = | - | 9400 119 |
Convert the result to decimal form :
| x | = | - 78.991597 |
