Work: Find the solution of equation （39.402+x）×2.15 = 39.402+72.104-x .
Question type: Equation
Solution:Original question:
| ( | 19701 500 | + | x | ) | × | 43 20 | = | 19701 500 | + | 9013 125 | − | x |
| Left side of the equation = | 19701 500 | × | 43 20 | + | x | × | 43 20 |
| = | 847143 10000 | + | x | × | 43 20 |
847143 10000 | + | 43 20 | x | = | 19701 500 | + | 9013 125 | − | x |
| Right side of the equation = | 55753 500 | − | x |
847143 10000 | + | 43 20 | x | = | 55753 500 | − | x |
Transposition :
43 20 | x | + | x | = | 55753 500 | − | 847143 10000 |
Combine the items on the left of the equation:
63 20 | x | = | 55753 500 | − | 847143 10000 |
Combine the items on the right of the equation:
63 20 | x | = | 267917 10000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 267917 10000 | ÷ | 63 20 |
| = | 267917 10000 | × | 20 63 |
| = | 267917 500 | × | 1 63 |
We obtained :
| x | = | 267917 31500 |
Convert the result to decimal form :
| x | = | 8.505302 |
