Work: Find the solution of equation (61780-9000*5-1728.57*4-x)*0.03-214.49 = 29.62+30 .
Question type: Equation
Solution:Original question:
| ( | 61780 | − | 9000 | × | 5 | − | 172857 100 | × | 4 | − | x | ) | × | 3 100 | − | 21449 100 | = | 1481 50 | + | 30 |
| Left side of the equation = | 61780 | × | 3 100 | − | 9000 | × | 5 | × | 3 100 | − | 172857 100 | × | 4 | × | 3 100 | − | x | × | 3 100 | − | 21449 100 |
| = | 9267 5 | − | 1350 | − | 518571 2500 | − | x | × | 3 100 | − | 21449 100 |
| = | 50926 625 | − | 3 100 | x |
50926 625 | − | 3 100 | x | = | 1481 50 | + | 30 |
| Right side of the equation = | 2981 50 |
50926 625 | − | 3 100 | x | = | 2981 50 |
Transposition :
| - | 3 100 | x | = | 2981 50 | − | 50926 625 |
Combine the items on the right of the equation:
| - | 3 100 | x | = | - | 27327 1250 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
27327 1250 | = | 3 100 | x |
If the left side of the equation is equal to the right side, then the right side must also be equal to the left side, that is :
3 100 | x | = | 27327 1250 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 27327 1250 | ÷ | 3 100 |
| = | 27327 1250 | × | 100 3 |
| = | 9109 25 | × | 2 |
We obtained :
| x | = | 18218 25 |
Convert the result to decimal form :
| x | = | 728.72 |
