[ 1/1 Equation]
Work: Find the solution of equation 1.25*(13.23%-F) = 0.87*(9.67%-F) .
Question type: Equation
Solution:Original question:
5 4 | ( | 1323 10000 | − | F | ) | = | 87 100 | ( | 967 10000 | − | F | ) |
| Left side of the equation = | 5 4 | × | 1323 10000 | − | 5 4 | F |
| = | 1323 8000 | − | 5 4 | F |
1323 8000 | − | 5 4 | F | = | 87 100 | ( | 967 10000 | − | F | ) |
| Right side of the equation = | 87 100 | × | 967 10000 | − | 87 100 | F |
| = | 84129 1000000 | − | 87 100 | F |
1323 8000 | − | 5 4 | F | = | 84129 1000000 | − | 87 100 | F |
Transposition :
| - | 5 4 | F | + | 87 100 | F | = | 84129 1000000 | − | 1323 8000 |
Combine the items on the left of the equation:
| - | 19 50 | F | = | 84129 1000000 | − | 1323 8000 |
Combine the items on the right of the equation:
| - | 19 50 | F | = | - | 40623 500000 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
40623 500000 | = | 19 50 | F |
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 :
19 50 | F | = | 40623 500000 |
The coefficient of the unknown number is reduced to 1 :
| F | = | 40623 500000 | ÷ | 19 50 |
| = | 40623 500000 | × | 50 19 |
| = | 40623 10000 | × | 1 19 |
We obtained :
| F | = | 40623 190000 |
Convert the result to decimal form :
| F | = | 0.213805 |
