Work: Find the solution of equation 0.64+0.36*(x*(0.95*70+5)+0.5)/0.5 = 0.64+0.36*5.09/0.8 .
Question type: Equation
Solution:Original question:
16 25 | + | 9 25 | ( | x | ( | 19 20 | × | 70 | + | 5 | ) | + | 1 2 | ) | ÷ | 1 2 | = | 16 25 | + | 9 25 | × | 509 100 | ÷ | 4 5 |
| Left side of the equation = | 16 25 | + | 18 25 | ( | x | ( | 19 20 | × | 70 | + | 5 | ) | + | 1 2 | ) |
16 25 | + | 18 25 | ( | x | ( | 19 20 | × | 70 | + | 5 | ) | + | 1 2 | ) | = | 16 25 | + | 9 25 | × | 509 100 | ÷ | 4 5 |
| Left side of the equation = | 16 25 | + | 18 25 | x | ( | 19 20 | × | 70 | + | 5 | ) | + | 18 25 | × | 1 2 |
| = | 16 25 | + | 18 25 | x | ( | 19 20 | × | 70 | + | 5 | ) | + | 9 25 |
| = | 1 | + | 18 25 | x | ( | 19 20 | × | 70 | + | 5 | ) |
| = | 1 | + | 18 25 | x | × | 19 20 | × | 70 | + | 18 25 | x | × | 5 |
| = | 1 | + | 1197 25 | x | + | 18 5 | x |
| = | 1 | + | 1287 25 | x |
| 1 | + | 1287 25 | x | = | 16 25 | + | 9 25 | × | 509 100 | ÷ | 4 5 |
| Right side of the equation = | 16 25 | + | 4581 2000 |
| = | 5861 2000 |
| 1 | + | 1287 25 | x | = | 5861 2000 |
Transposition :
1287 25 | x | = | 5861 2000 | − | 1 |
Combine the items on the right of the equation:
1287 25 | x | = | 3861 2000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 3861 2000 | ÷ | 1287 25 |
| = | 3861 2000 | × | 25 1287 |
| = | 3 80 | × | 1 |
We obtained :
| x | = | 3 80 |
Convert the result to decimal form :
| x | = | 0.0375 |
