Work: Find the solution of equation [7y-（210-14+183.36+0+83.2+5+0）]*0.75+183.36 = 260 .
Question type: Equation
Solution:Original question:
| ( | 7 | y | − | ( | 210 | − | 14 | + | 4584 25 | + | 0 | + | 416 5 | + | 5 | + | 0 | ) | ) | × | 3 4 | + | 4584 25 | = | 260 |
| Left side of the equation = | 7 | y | × | 3 4 | − | ( | 210 | − | 14 | + | 4584 25 | + | 0 | + | 416 5 | + | 5 | + | 0 | ) | × | 3 4 | + | 4584 25 |
| = | 21 4 | y | − | ( | 210 | − | 14 | + | 4584 25 | + | 0 | + | 416 5 | + | 5 | + | 0 | ) | × | 3 4 | + | 4584 25 |
| = | 21 4 | y | − | 210 | × | 3 4 | + | 14 | × | 3 4 | − | 4584 25 | × | 3 4 | − | 0 | × | 3 4 | − | 416 5 | × | 3 4 |
| = | 21 4 | y | − | 315 2 | + | 21 2 | − | 3438 25 | − | 0 | − | 312 5 | − | 15 4 | − | 0 | + | 4584 25 |
| = | 21 4 | y | − | 16731 100 |
21 4 | y | − | 16731 100 | = | 260 |
Transposition :
21 4 | y | = | 260 | + | 16731 100 |
Combine the items on the right of the equation:
21 4 | y | = | 42731 100 |
The coefficient of the unknown number is reduced to 1 :
| y | = | 42731 100 | ÷ | 21 4 |
| = | 42731 100 | × | 4 21 |
| = | 42731 25 | × | 1 21 |
We obtained :
| y | = | 42731 525 |
Convert the result to decimal form :
| y | = | 81.392381 |
