[ 1/1 Equation]
Work: Find the solution of equation 7y-[(210-14)+183.36+(1040*8%+100*5%)] = 102.19 .
Question type: Equation
Solution:Original question:
| 7 | y | − | ( | ( | 210 | − | 14 | ) | + | 4584 25 | + | ( | 1040 | × | 8 100 | + | 100 | × | 5 100 | ) | ) | = | 10219 100 |
| Left side of the equation = | 7 | y | − | ( | 210 | − | 14 | ) | − | 4584 25 | − | ( | 1040 | × | 8 100 | + | 100 | × | 5 100 | ) |
| = | 7 | y | − | 210 | + | 14 | − | 4584 25 | − | ( | 1040 | × | 8 100 | + | 100 | × | 5 100 | ) |
| = | 7 | y | − | 9484 25 | − | ( | 1040 | × | 8 100 | + | 100 | × | 5 100 | ) |
| = | 7 | y | − | 9484 25 | − | 1040 | × | 8 100 | − | 100 | × | 5 100 |
| = | 7 | y | − | 9484 25 | − | 416 5 | − | 5 |
| = | 7 | y | − | 11689 25 |
| 7 | y | − | 11689 25 | = | 10219 100 |
Transposition :
| 7 | y | = | 10219 100 | + | 11689 25 |
Combine the items on the right of the equation:
| 7 | y | = | 2279 4 |
The coefficient of the unknown number is reduced to 1 :
| y | = | 2279 4 | ÷ | 7 |
| = | 2279 4 | × | 1 7 |
We obtained :
| y | = | 2279 28 |
Convert the result to decimal form :
| y | = | 81.392857 |
