Work: Find the solution of equation 56.1/2+（（40+38+x）/3）/3 = 50 .
Question type: Equation
Solution:Original question:
561 10 | ÷ | 2 | + | ( | ( | 40 | + | 38 | + | x | ) | ÷ | 3 | ) | ÷ | 3 | = | 50 |
| Left side of the equation = | 561 20 | + | ( | ( | 40 | + | 38 | + | x | ) | ÷ | 3 | ) | × | 1 3 |
561 20 | + | ( | ( | 40 | + | 38 | + | x | ) | ÷ | 3 | ) | × | 1 3 | = | 50 |
| Left side of the equation = | 561 20 | + | ( | 40 | + | 38 | + | x | ) | ÷ | 3 | × | 1 3 |
| = | 561 20 | + | ( | 40 | + | 38 | + | x | ) | × | 1 9 |
| = | 561 20 | + | 40 | × | 1 9 | + | 38 | × | 1 9 | + | x | × | 1 9 |
| = | 561 20 | + | 40 9 | + | 38 9 | + | x | × | 1 9 |
| = | 2203 60 | + | 1 9 | x |
2203 60 | + | 1 9 | x | = | 50 |
Transposition :
1 9 | x | = | 50 | − | 2203 60 |
Combine the items on the right of the equation:
1 9 | x | = | 797 60 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 797 60 | ÷ | 1 9 |
| = | 797 60 | × | 9 |
| = | 797 20 | × | 3 |
We obtained :
| x | = | 2391 20 |
Convert the result to decimal form :
| x | = | 119.55 |
