Work: Find the solution of equation （x+800-(2500+5213.15-4455.78）)*0.75 = 0.05 .
Question type: Equation
Solution:Original question:
| ( | x | + | 800 | − | ( | 2500 | + | 104263 20 | − | 222789 50 | ) | ) | × | 3 4 | = | 1 20 |
| Left side of the equation = | x | × | 3 4 | + | 800 | × | 3 4 | − | ( | 2500 | + | 104263 20 | − | 222789 50 | ) | × | 3 4 |
| = | x | × | 3 4 | + | 600 | − | ( | 2500 | + | 104263 20 | − | 222789 50 | ) | × | 3 4 |
| = | 3 4 | x | + | 600 | − | 2500 | × | 3 4 | − | 104263 20 | × | 3 4 | + | 222789 50 | × | 3 4 |
| = | 3 4 | x | + | 600 | − | 1875 | − | 312789 80 | + | 668367 200 |
| = | 3 4 | x | − | 737211 400 |
3 4 | x | − | 737211 400 | = | 1 20 |
Transposition :
3 4 | x | = | 1 20 | + | 737211 400 |
Combine the items on the right of the equation:
3 4 | x | = | 737231 400 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 737231 400 | ÷ | 3 4 |
| = | 737231 400 | × | 4 3 |
| = | 737231 100 | × | 1 3 |
We obtained :
| x | = | 737231 300 |
Convert the result to decimal form :
| x | = | 2457.436667 |
