Work: Find the solution of equation x:(5.4-x) = 5:4 .
Question type: Equation
Solution:Original question:
| x | ÷ | ( | 27 5 | − | x | ) | = | 5 | ÷ | 4 |
| Multiply both sides of the equation by: | ( | 27 5 | − | x | ) |
| x | = | 5 | ÷ | 4 | × | ( | 27 5 | − | x | ) |
| x | = | 5 | ÷ | 4 | × | 27 5 | − | 5 | ÷ | 4 | × | x |
| x | = | 27 4 | − | 5 4 | x |
Transposition :
| x | + | 5 4 | x | = | 27 4 |
Combine the items on the left of the equation:
9 4 | x | = | 27 4 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 27 4 | ÷ | 9 4 |
| = | 27 4 | × | 4 9 |
| = | 3 | × | 1 |
We obtained :
| x | = | 3 |
