Work: Find the solution of equation (x+367751.27-45000)*0.25-31920 = x+50446.46 .
Question type: Equation
Solution:Original question:
| ( | x | + | 36775127 100 | − | 45000 | ) | × | 1 4 | − | 31920 | = | x | + | 2522323 50 |
| Left side of the equation = | x | × | 1 4 | + | 36775127 100 | × | 1 4 | − | 45000 | × | 1 4 | − | 31920 |
| = | x | × | 1 4 | + | 36775127 400 | − | 11250 | − | 31920 |
| = | 1 4 | x | + | 19507127 400 |
1 4 | x | + | 19507127 400 | = | x | + | 2522323 50 |
Transposition :
1 4 | x | − | x | = | 2522323 50 | − | 19507127 400 |
Combine the items on the left of the equation:
| - | 3 4 | x | = | 2522323 50 | − | 19507127 400 |
Combine the items on the right of the equation:
| - | 3 4 | x | = | 671457 400 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
| - | 671457 400 | = | 3 4 | 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 4 | x | = | - | 671457 400 |
The coefficient of the unknown number is reduced to 1 :
| x | = | - | 671457 400 | ÷ | 3 4 |
| = | - | 671457 400 | × | 4 3 |
| = | - | 223819 100 | × | 1 |
We obtained :
| x | = | - | 223819 100 |
Convert the result to decimal form :
| x | = | - 2238.19 |
