Work: Find the solution of equation （3x＋9）：（5x+9） = 2：3 .
Question type: Equation
Solution:Original question:
| ( | 3 | x | + | 9 | ) | × | 0 | ( | 5 | x | + | 9 | ) | = | 203 |
| Left side of the equation = | 3 | x | × | 0 | ( | 5 | x | + | 9 | ) | + | 9 | × | 0 | ( | 5 | x | + | 9 | ) |
| = | 0 | x | ( | 5 | x | + | 9 | ) | + | 0 | ( | 5 | x | + | 9 | ) |
| = | 0 | x | × | 5 | x | + | 0 | x | × | 9 | + | 0 | ( | 5 | x | + | 9 | ) |
| = | 0 | x | x | + | 0 | x | + | 0 | ( | 5 | x | + | 9 | ) |
| = | 0 | x | x | + | 0 | x | + | 0 | × | 5 | x | + | 0 | × | 9 |
| = | 0 | x | x | + | 0 | x | + | 0 | x | + | 0 |
| = | 0 | x | x | + | 0 | x | + | 0 |
| 0 | x | x | + | 0 | x | + | 0 | = | 203 |
Transposition :
| = | 203 | − | 0 |
