[ 1/1 Equation]
Work: Find the solution of equation 3351*(1+x/100-0.89)-611 = 3418*(1+x/100-1.11) .
Question type: Equation
Solution:Original question:
| 3351 | ( | 1 | + | x | ÷ | 100 | − | 89 100 | ) | − | 611 | = | 3418 | ( | 1 | + | x | ÷ | 100 | − | 111 100 | ) |
| Left side of the equation = | 3351 | × | 1 | + | 3351 | x | ÷ | 100 | − | 3351 | × | 89 100 | − | 611 |
| = | 3351 | + | 3351 100 | x | − | 298239 100 | − | 611 |
| = | - | 24239 100 | + | 3351 100 | x |
| - | 24239 100 | + | 3351 100 | x | = | 3418 | ( | 1 | + | x | ÷ | 100 | − | 111 100 | ) |
| Right side of the equation = | 3418 | × | 1 | + | 3418 | x | ÷ | 100 | − | 3418 | × | 111 100 |
| = | 3418 | + | 1709 50 | x | − | 189699 50 |
| = | - | 18799 50 | + | 1709 50 | x |
| - | 24239 100 | + | 3351 100 | x | = | - | 18799 50 | + | 1709 50 | x |
Transposition :
3351 100 | x | − | 1709 50 | x | = | - | 18799 50 | + | 24239 100 |
Combine the items on the left of the equation:
| - | 67 100 | x | = | - | 18799 50 | + | 24239 100 |
Combine the items on the right of the equation:
| - | 67 100 | x | = | - | 13359 100 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
13359 100 | = | 67 100 | 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 :
67 100 | x | = | 13359 100 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 13359 100 | ÷ | 67 100 |
| = | 13359 100 | × | 100 67 |
| = | 13359 | × | 1 67 |
We obtained :
| x | = | 13359 67 |
Convert the result to decimal form :
| x | = | 199.38806 |
