Work: Find the solution of equation 574*（1+X）/87% = 132.99 .
Question type: Equation
Solution:Original question:
| 574 | ( | 1 | + | X | ) | ÷ | 87 100 | = | 13299 100 |
| Left side of the equation = | 57400 87 | ( | 1 | + | X | ) |
57400 87 | ( | 1 | + | X | ) | = | 13299 100 |
| Left side of the equation = | 57400 87 | × | 1 | + | 57400 87 | X |
| = | 57400 87 | + | 57400 87 | X |
57400 87 | + | 57400 87 | X | = | 13299 100 |
Transposition :
57400 87 | X | = | 13299 100 | − | 57400 87 |
Combine the items on the right of the equation:
57400 87 | X | = | - | 4582987 8700 |
The coefficient of the unknown number is reduced to 1 :
| X | = | - | 4582987 8700 | ÷ | 57400 87 |
| = | - | 4582987 8700 | × | 87 57400 |
| = | - | 4582987 100 | × | 1 57400 |
We obtained :
| X | = | - | 4582987 5740000 |
Convert the result to decimal form :
| X | = | - 0.79843 |
