[ 1/1 Equation]
Work: Find the solution of equation 30 = 22+(x-22)(0.064+0.105+0.06)+50*0.7 .
Question type: Equation
Solution:Original question:
| 30 | = | 22 | + | ( | x | − | 22 | ) | ( | 8 125 | + | 21 200 | + | 3 50 | ) | + | 50 | × | 7 10 |
| Right side of the equation = | 22 | + | ( | x | − | 22 | ) | ( | 8 125 | + | 21 200 | + | 3 50 | ) | + | 35 |
| = | 57 | + | ( | x | − | 22 | ) | ( | 8 125 | + | 21 200 | + | 3 50 | ) |
| 30 | = | 57 | + | ( | x | − | 22 | ) | ( | 8 125 | + | 21 200 | + | 3 50 | ) |
| Right side of the equation = | 57 | + | x | ( | 8 125 | + | 21 200 | + | 3 50 | ) | − | 22 | ( | 8 125 | + | 21 200 | + | 3 50 | ) |
| = | 57 | + | x | × | 8 125 | + | x | × | 21 200 | + | x | × | 3 50 | − | 22 | ( | 8 125 | + | 21 200 | + | 3 50 | ) |
| = | 57 | + | 229 1000 | x | − | 22 | ( | 8 125 | + | 21 200 | + | 3 50 | ) |
| = | 57 | + | 229 1000 | x | − | 22 | × | 8 125 | − | 22 | × | 21 200 | − | 22 | × | 3 50 |
| = | 57 | + | 229 1000 | x | − | 176 125 | − | 231 100 | − | 33 25 |
| = | 25981 500 | + | 229 1000 | x |
| 30 | = | 25981 500 | + | 229 1000 | x |
Transposition :
| - | 229 1000 | x | = | 25981 500 | − | 30 |
Combine the items on the right of the equation:
| - | 229 1000 | x | = | 10981 500 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
| - | 10981 500 | = | 229 1000 | x |
If the left side of the equation is equal to the right side, then the right side must also be equal to the left side, that is :
229 1000 | x | = | - | 10981 500 |
The coefficient of the unknown number is reduced to 1 :
| x | = | - | 10981 500 | ÷ | 229 1000 |
| = | - | 10981 500 | × | 1000 229 |
| = | - | 10981 | × | 2 229 |
We obtained :
| x | = | - | 21962 229 |
Convert the result to decimal form :
| x | = | - 95.90393 |
