[ 1/1 Equation]
Work: Find the solution of equation （25.851+x）×2.55 = 51.702+69.853-x .
Question type: Equation
Solution:Original question:
| ( | 25851 1000 | + | x | ) | × | 51 20 | = | 25851 500 | + | 69853 1000 | − | x |
| Left side of the equation = | 25851 1000 | × | 51 20 | + | x | × | 51 20 |
| = | 1318401 20000 | + | x | × | 51 20 |
1318401 20000 | + | 51 20 | x | = | 25851 500 | + | 69853 1000 | − | x |
| Right side of the equation = | 24311 200 | − | x |
1318401 20000 | + | 51 20 | x | = | 24311 200 | − | x |
Transposition :
51 20 | x | + | x | = | 24311 200 | − | 1318401 20000 |
Combine the items on the left of the equation:
71 20 | x | = | 24311 200 | − | 1318401 20000 |
Combine the items on the right of the equation:
71 20 | x | = | 1112699 20000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 1112699 20000 | ÷ | 71 20 |
| = | 1112699 20000 | × | 20 71 |
| = | 1112699 1000 | × | 1 71 |
We obtained :
| x | = | 1112699 71000 |
Convert the result to decimal form :
| x | = | 15.671817 |
