Work: Find the solution of equation 1.03x+1100+100+100+(1.03x+1100+100+100)*0.15 = 6892.6 .
Question type: Equation
Solution:Original question:
103 100 | x | + | 1100 | + | 100 | + | 100 | + | ( | 103 100 | x | + | 1100 | + | 100 | + | 100 | ) | × | 3 20 | = | 34463 5 |
| Left side of the equation = | 103 100 | x | + | 1300 | + | ( | 103 100 | x | + | 1100 | + | 100 | + | 100 | ) | × | 3 20 |
103 100 | x | + | 1300 | + | ( | 103 100 | x | + | 1100 | + | 100 | + | 100 | ) | × | 3 20 | = | 34463 5 |
| Left side of the equation = | 103 100 | x | + | 1300 | + | 103 100 | x | × | 3 20 | + | 1100 | × | 3 20 | + | 100 | × | 3 20 | + | 100 | × | 3 20 |
| = | 103 100 | x | + | 1300 | + | 309 2000 | x | + | 165 | + | 15 | + | 15 |
| = | 2369 2000 | x | + | 1495 |
2369 2000 | x | + | 1495 | = | 34463 5 |
Transposition :
2369 2000 | x | = | 34463 5 | − | 1495 |
Combine the items on the right of the equation:
2369 2000 | x | = | 26988 5 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 26988 5 | ÷ | 2369 2000 |
| = | 26988 5 | × | 2000 2369 |
| = | 26988 | × | 400 2369 |
We obtained :
| x | = | 10795200 2369 |
Convert the result to decimal form :
| x | = | 4556.859434 |
