Work: Find the solution of equation 282.28÷300×100×70％+x÷750×100×30％ = 0 .
Question type: Equation
Solution:Original question:
7057 25 | ÷ | 300 | × | 100 | × | 70 100 | + | x | ÷ | 750 | × | 100 | × | 30 100 | = | 0 |
| Left side of the equation = | 49399 750 | + | x | × | 1 25 |
49399 750 | + | 1 25 | x | = | 0 |
Transposition :
1 25 | x | = | 0 | − | 49399 750 |
Combine the items on the right of the equation:
1 25 | x | = | - | 49399 750 |
The coefficient of the unknown number is reduced to 1 :
| x | = | - | 49399 750 | ÷ | 1 25 |
| = | - | 49399 750 | × | 25 |
| = | - | 49399 30 | × | 1 |
We obtained :
| x | = | - | 49399 30 |
Convert the result to decimal form :
| x | = | - 1646.633333 |
