[ 1/1 Equation]
Work: Find the solution of equation （41.789+x)×1.45 = 72.868+41.789-x .
Question type: Equation
Solution:Original question:
| ( | 41789 1000 | + | x | ) | × | 29 20 | = | 18217 250 | + | 41789 1000 | − | x |
| Left side of the equation = | 41789 1000 | × | 29 20 | + | x | × | 29 20 |
| = | 1211881 20000 | + | x | × | 29 20 |
1211881 20000 | + | 29 20 | x | = | 18217 250 | + | 41789 1000 | − | x |
| Right side of the equation = | 114657 1000 | − | x |
1211881 20000 | + | 29 20 | x | = | 114657 1000 | − | x |
Transposition :
29 20 | x | + | x | = | 114657 1000 | − | 1211881 20000 |
Combine the items on the left of the equation:
49 20 | x | = | 114657 1000 | − | 1211881 20000 |
Combine the items on the right of the equation:
49 20 | x | = | 1081259 20000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 1081259 20000 | ÷ | 49 20 |
| = | 1081259 20000 | × | 20 49 |
| = | 1081259 1000 | × | 1 49 |
We obtained :
| x | = | 1081259 49000 |
Convert the result to decimal form :
| x | = | 22.06651 |
