Work: Find the solution of equation 1429 = 65.5+94*1550*(1/750x+7/3750)+429x .
Question type: Equation
Solution:Original question:
| 1429 | = | 131 2 | + | 94 | × | 1550 | ( | 1 | ÷ | 750 | × | x | + | 7 | ÷ | 3750 | ) | + | 429 | x |
| Right side of the equation = | 131 2 | + | 145700 | ( | 1 | ÷ | 750 | × | x | + | 7 | ÷ | 3750 | ) | + | 429 | x |
| 1429 | = | 131 2 | + | 145700 | ( | 1 | ÷ | 750 | × | x | + | 7 | ÷ | 3750 | ) | + | 429 | x |
| Right side of the equation = | 131 2 | + | 145700 | × | 1 | ÷ | 750 | × | x | + | 145700 | × | 7 | ÷ | 3750 | + | 429 | x |
| = | 131 2 | + | 2914 15 | x | + | 20398 75 | + | 429 | x |
| = | 50621 150 | + | 9349 15 | x |
| 1429 | = | 50621 150 | + | 9349 15 | x |
Transposition :
| - | 9349 15 | x | = | 50621 150 | − | 1429 |
Combine the items on the right of the equation:
| - | 9349 15 | x | = | - | 163729 150 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
163729 150 | = | 9349 15 | 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 :
9349 15 | x | = | 163729 150 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 163729 150 | ÷ | 9349 15 |
| = | 163729 150 | × | 15 9349 |
| = | 163729 10 | × | 1 9349 |
We obtained :
| x | = | 163729 93490 |
Convert the result to decimal form :
| x | = | 1.7513 |
