Work: Find the solution of equation (78-75.3)/0.1 = (78-x)/(0.3-0.2727) .
Question type: Equation
Solution:Original question:
| ( | 78 | − | 753 10 | ) | ÷ | 1 10 | = | ( | 78 | − | x | ) | ÷ | ( | 3 10 | − | 2727 10000 | ) |
| Multiply both sides of the equation by: | ( | 3 10 | − | 2727 10000 | ) |
| ( | 78 | − | 753 10 | ) | ÷ | 1 10 | × | ( | 3 10 | − | 2727 10000 | ) | = | ( | 78 | − | x | ) |
| 78 | ÷ | 1 10 | × | ( | 3 10 | − | 2727 10000 | ) | − | 753 10 | ÷ | 1 10 | × | ( | 3 10 | − | 2727 10000 | ) | = | ( | 78 | − | x | ) |
| 78 | ÷ | 1 10 | × | ( | 3 10 | − | 2727 10000 | ) | − | 753 10 | ÷ | 1 10 | × | ( | 3 10 | − | 2727 10000 | ) | = | 78 | − | x |
| 780 | ( | 3 10 | − | 2727 10000 | ) | − | 753 | ( | 3 10 | − | 2727 10000 | ) | = | 78 | − | x |
| 780 | × | 3 10 | − | 780 | × | 2727 10000 | − | 753 | ( | 3 10 | − | 2727 10000 | ) | = | 78 | − | x |
| 234 | − | 106353 500 | − | 753 | ( | 3 10 | − | 2727 10000 | ) | = | 78 | − | x |
10647 500 | − | 753 | ( | 3 10 | − | 2727 10000 | ) | = | 78 | − | x |
10647 500 | − | 753 | × | 3 10 | + | 753 | × | 2727 10000 | = | 78 | − | x |
10647 500 | − | 2259 10 | + | 2053431 10000 | = | 78 | − | x |
7371 10000 | = | 78 | − | x |
Transposition :
| x | = | 78 | − | 7371 10000 |
Combine the items on the right of the equation:
| x | = | 772629 10000 |
This is the solution of the equation.
