Work: Find the solution of equation 43986000+222720+x*0.77%+(x*1.06-30000000)*0.15%+90000 = x .
Question type: Equation
Solution:Original question:
| 43986000 | + | 222720 | + | x | × | 77 10000 | + | ( | x | × | 53 50 | − | 30000000 | ) | × | 3 2000 | + | 90000 | = | x |
| Left side of the equation = | 44298720 | + | 77 10000 | x | + | ( | x | × | 53 50 | − | 30000000 | ) | × | 3 2000 |
| 44298720 | + | 77 10000 | x | + | ( | x | × | 53 50 | − | 30000000 | ) | × | 3 2000 | = | x |
| Left side of the equation = | 44298720 | + | 77 10000 | x | + | x | × | 53 50 | × | 3 2000 | − | 30000000 | × | 3 2000 |
| = | 44298720 | + | 77 10000 | x | + | x | × | 159 100000 | − | 45000 |
| = | 44253720 | + | 929 100000 | x |
| 44253720 | + | 929 100000 | x | = | x |
Transposition :
929 100000 | x | − | x | = | - | 44253720 |
Combine the items on the left of the equation:
| - | 99071 100000 | x | = | - | 44253720 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
| 44253720 | = | 99071 100000 | 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 :
99071 100000 | x | = | 44253720 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 44253720 | ÷ | 99071 100000 |
| = | 44253720 | × | 100000 99071 |
| = | 6321960 | × | 100000 14153 |
We obtained :
| x | = | 632196000000 14153 |
