Work: Find the solution of equation （38.584+x）×2.8 = 38.584+68.718-x .
Question type: Equation
Solution:Original question:
| ( | 4823 125 | + | x | ) | × | 14 5 | = | 4823 125 | + | 34359 500 | − | x |
| Left side of the equation = | 4823 125 | × | 14 5 | + | x | × | 14 5 |
| = | 67522 625 | + | x | × | 14 5 |
67522 625 | + | 14 5 | x | = | 4823 125 | + | 34359 500 | − | x |
| Right side of the equation = | 53651 500 | − | x |
67522 625 | + | 14 5 | x | = | 53651 500 | − | x |
Transposition :
14 5 | x | + | x | = | 53651 500 | − | 67522 625 |
Combine the items on the left of the equation:
19 5 | x | = | 53651 500 | − | 67522 625 |
Combine the items on the right of the equation:
19 5 | x | = | - | 1833 2500 |
The coefficient of the unknown number is reduced to 1 :
| x | = | - | 1833 2500 | ÷ | 19 5 |
| = | - | 1833 2500 | × | 5 19 |
| = | - | 1833 500 | × | 1 19 |
We obtained :
| x | = | - | 1833 9500 |
Convert the result to decimal form :
| x | = | - 0.192947 |
