[ 1/1 Equation]
Work: Find the solution of equation （39.402+x）×1.95 = 39.402+71.604-x .
Question type: Equation
Solution:Original question:
| ( | 19701 500 | + | x | ) | × | 39 20 | = | 19701 500 | + | 17901 250 | − | x |
| Left side of the equation = | 19701 500 | × | 39 20 | + | x | × | 39 20 |
| = | 768339 10000 | + | x | × | 39 20 |
768339 10000 | + | 39 20 | x | = | 19701 500 | + | 17901 250 | − | x |
| Right side of the equation = | 55503 500 | − | x |
768339 10000 | + | 39 20 | x | = | 55503 500 | − | x |
Transposition :
39 20 | x | + | x | = | 55503 500 | − | 768339 10000 |
Combine the items on the left of the equation:
59 20 | x | = | 55503 500 | − | 768339 10000 |
Combine the items on the right of the equation:
59 20 | x | = | 341721 10000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 341721 10000 | ÷ | 59 20 |
| = | 341721 10000 | × | 20 59 |
| = | 341721 500 | × | 1 59 |
We obtained :
| x | = | 341721 29500 |
Convert the result to decimal form :
| x | = | 11.583763 |
