Work: Find the solution of equation 15/89.14+30/1650+X/1000+(49.7-X)/200 = 0.363 .
Question type: Equation
Solution:Original question:
| 15 | ÷ | 4457 50 | + | 30 | ÷ | 1650 | + | X | ÷ | 1000 | + | ( | 497 10 | − | X | ) | ÷ | 200 | = | 363 1000 |
| Left side of the equation = | 750 4457 | + | 1 55 | + | X | × | 1 1000 | + | ( | 497 10 | − | X | ) | × | 1 200 |
| = | 45707 245135 | + | 1 1000 | X | + | ( | 497 10 | − | X | ) | × | 1 200 |
45707 245135 | + | 1 1000 | X | + | ( | 497 10 | − | X | ) | × | 1 200 | = | 363 1000 |
| Left side of the equation = | 45707 245135 | + | 1 1000 | X | + | 497 10 | × | 1 200 | − | X | × | 1 200 |
| = | 45707 245135 | + | 1 1000 | X | + | 497 2000 | − | X | × | 1 200 |
| = | 42649219 98054000 | − | 1 250 | X |
42649219 98054000 | − | 1 250 | X | = | 363 1000 |
Transposition :
| - | 1 250 | X | = | 363 1000 | − | 42649219 98054000 |
