Work: Find the solution of equation 0.137（R/19.28）-3+0.119（R/19.28）-2+0.269（R/19.28）-1 = 0.453 .
Question type: Equation
Solution:Original question:
137 1000 | ( | R | ÷ | 482 25 | ) | − | 3 | + | 119 1000 | ( | R | ÷ | 482 25 | ) | − | 2 | + | 269 1000 | ( | R | ÷ | 482 25 | ) | − | 1 | = | 453 1000 |
| Left side of the equation = | 137 1000 | ( | R | ÷ | 482 25 | ) | − | 6 | + | 119 1000 | ( | R | ÷ | 482 25 | ) | + | 269 1000 | ( | R | ÷ | 482 25 | ) |
137 1000 | ( | R | ÷ | 482 25 | ) | − | 6 | + | 119 1000 | ( | R | ÷ | 482 25 | ) | + | 269 1000 | ( | R | ÷ | 482 25 | ) | = | 453 1000 |
| Left side of the equation = | 137 1000 | R | ÷ | 482 25 | − | 6 | + | 119 1000 | ( | R | ÷ | 482 25 | ) | + | 269 1000 | ( | R | ÷ | 482 25 | ) |
| = | 137 19280 | R | − | 6 | + | 119 1000 | ( | R | ÷ | 482 25 | ) | + | 269 1000 | ( | R | ÷ | 482 25 | ) |
| = | 137 19280 | R | − | 6 | + | 119 1000 | R | ÷ | 482 25 | + | 269 1000 | ( | R | ÷ | 482 25 | ) |
| = | 137 19280 | R | − | 6 | + | 119 19280 | R | + | 269 1000 | ( | R | ÷ | 482 25 | ) |
| = | 16 1205 | R | − | 6 | + | 269 1000 | ( | R | ÷ | 482 25 | ) |
| = | 16 1205 | R | − | 6 | + | 269 1000 | R | ÷ | 482 25 |
| = | 16 1205 | R | − | 6 | + | 269 19280 | R |
| = | 25305 929296 | R | − | 6 |
25305 929296 | R | − | 6 | = | 453 1000 |
Transposition :
25305 929296 | R | = | 453 1000 | + | 6 |
Combine the items on the right of the equation:
25305 929296 | R | = | 6453 1000 |
The coefficient of the unknown number is reduced to 1 :
| R | = | 6453 1000 | ÷ | 25305 929296 |
| = | 6453 1000 | × | 929296 25305 |
| = | 2151 125 | × | 116162 8435 |
We obtained :
| R | = | 249864462 1054375 |
By reducing fraction, we can get:
| R | = | 1036782 4375 |
Convert the result to decimal form :
| R | = | 236.978743 |
