[ 1/1 Equation]
Work: Find the solution of equation (x*(0.95*70+0.05*5)+(1-x)*0.8)*0.36+0.64 = 0.64+0.36*1.12/0.5 .
Question type: Equation
Solution:Original question:
| ( | x | ( | 19 20 | × | 70 | + | 1 20 | × | 5 | ) | + | ( | 1 | − | x | ) | × | 4 5 | ) | × | 9 25 | + | 16 25 | = | 16 25 | + | 9 25 | × | 28 25 | ÷ | 1 2 |
| Left side of the equation = | x | ( | 19 20 | × | 70 | + | 1 20 | × | 5 | ) | × | 9 25 | + | ( | 1 | − | x | ) | × | 4 5 | × | 9 25 | + | 16 25 |
| = | x | ( | 19 20 | × | 70 | + | 1 20 | × | 5 | ) | × | 9 25 | + | ( | 1 | − | x | ) | × | 36 125 | + | 16 25 |
| = | x | × | 19 20 | × | 70 | × | 9 25 | + | x | × | 1 20 | × | 5 | × | 9 25 | + | ( | 1 | − | x | ) | × | 36 125 | + | 16 25 |
| = | x | × | 1197 50 | + | x | × | 9 100 | + | ( | 1 | − | x | ) | × | 36 125 | + | 16 25 |
| = | 2403 100 | x | + | ( | 1 | − | x | ) | × | 36 125 | + | 16 25 |
| = | 2403 100 | x | + | 1 | × | 36 125 | − | x | × | 36 125 | + | 16 25 |
| = | 2403 100 | x | + | 36 125 | − | x | × | 36 125 | + | 16 25 |
| = | 11871 500 | x | + | 116 125 |
11871 500 | x | + | 116 125 | = | 16 25 | + | 9 25 | × | 28 25 | ÷ | 1 2 |
| Right side of the equation = | 16 25 | + | 504 625 |
| = | 904 625 |
11871 500 | x | + | 116 125 | = | 904 625 |
Transposition :
11871 500 | x | = | 904 625 | − | 116 125 |
Combine the items on the right of the equation:
11871 500 | x | = | 324 625 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 324 625 | ÷ | 11871 500 |
| = | 324 625 | × | 500 11871 |
| = | 36 5 | × | 4 1319 |
We obtained :
| x | = | 144 6595 |
Convert the result to decimal form :
| x | = | 0.021835 |
