[ 1/1 Equation]
Work: Find the solution of equation （42.309+x）×1.55 = 42.309+88.995-x .
Question type: Equation
Solution:Original question:
| ( | 42309 1000 | + | x | ) | × | 31 20 | = | 42309 1000 | + | 17799 200 | − | x |
| Left side of the equation = | 42309 1000 | × | 31 20 | + | x | × | 31 20 |
| = | 1311579 20000 | + | x | × | 31 20 |
1311579 20000 | + | 31 20 | x | = | 42309 1000 | + | 17799 200 | − | x |
| Right side of the equation = | 16413 125 | − | x |
1311579 20000 | + | 31 20 | x | = | 16413 125 | − | x |
Transposition :
31 20 | x | + | x | = | 16413 125 | − | 1311579 20000 |
Combine the items on the left of the equation:
51 20 | x | = | 16413 125 | − | 1311579 20000 |
Combine the items on the right of the equation:
51 20 | x | = | 1314501 20000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 1314501 20000 | ÷ | 51 20 |
| = | 1314501 20000 | × | 20 51 |
| = | 438167 1000 | × | 1 17 |
We obtained :
| x | = | 438167 17000 |
Convert the result to decimal form :
| x | = | 25.774529 |
