Work: Find the solution of equation 88992.75-x-(7348.03-x/1.09*0.09)-(7348.03-x/1.09*0.09)-2669.78 = 0 .
Question type: Equation
Solution:Original question:
355971 4 | − | x | − | ( | 734803 100 | − | x | ÷ | 109 100 | × | 9 100 | ) | − | ( | 734803 100 | − | x | ÷ | 109 100 | × | 9 100 | ) | − | 133489 50 | = | 0 |
| Left side of the equation = | 8632297 100 | − | x | − | ( | 734803 100 | − | x | ÷ | 109 100 | × | 9 100 | ) | − | ( | 734803 100 | − | x | ÷ | 109 100 | × | 9 100 | ) |
8632297 100 | − | x | − | ( | 734803 100 | − | x | ÷ | 109 100 | × | 9 100 | ) | − | ( | 734803 100 | − | x | ÷ | 109 100 | × | 9 100 | ) | = | 0 |
| Left side of the equation = | 8632297 100 | − | x | − | 734803 100 | + | x | ÷ | 109 100 | × | 9 100 | − | ( | 734803 100 | − | x | ÷ | 109 100 | × | 9 100 | ) |
| = | 8632297 100 | − | x | − | 734803 100 | + | x | × | 9 109 | − | ( | 734803 100 | − | x | ÷ | 109 100 | × | 9 100 | ) |
| = | 3948747 50 | − | 100 109 | x | − | ( | 734803 100 | − | x | ÷ | 109 100 | × | 9 100 | ) |
| = | 3948747 50 | − | 100 109 | x | − | 734803 100 | + | x | ÷ | 109 100 | × | 9 100 |
| = | 3948747 50 | − | 100 109 | x | − | 734803 100 | + | x | × | 9 109 |
| = | 7162691 100 | − | 91 109 | x |
7162691 100 | − | 91 109 | x | = | 0 |
Transposition :
| - | 91 109 | x | = | 0 | − | 7162691 100 |
Combine the items on the right of the equation:
| - | 91 109 | x | = | - | 7162691 100 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
7162691 100 | = | 91 109 | 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 :
91 109 | x | = | 7162691 100 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 7162691 100 | ÷ | 91 109 |
| = | 7162691 100 | × | 109 91 |
We obtained :
| x | = | 780733319 9100 |
Convert the result to decimal form :
| x | = | 85794.87022 |
