( | 54 5 | y | + | 11000 | × | 141 10 | ) | ÷ | ( | y | + | 11000 | ) | = | 12 |
Multiply both sides of the equation by: | ( | y | + | 11000 | ) |
( | 54 5 | y | + | 11000 | × | 141 10 | ) | = | 12 | ( | y | + | 11000 | ) |
54 5 | y | + | 11000 | × | 141 10 | = | 12 | ( | y | + | 11000 | ) |
54 5 | y | + | 11000 | × | 141 10 | = | 12 | y | + | 12 | × | 11000 |
54 5 | y | + | 155100 | = | 12 | y | + | 132000 |
54 5 | y | − | 12 | y | = | 132000 | − | 155100 |
- | 6 5 | y | = | 132000 | − | 155100 |
- | 6 5 | y | = | - | 23100 |
23100 | = | 6 5 | y |
6 5 | y | = | 23100 |
y | = | 23100 | ÷ | 6 5 |
= | 23100 | × | 5 6 |
= | 3850 | × | 5 |
y | = | 19250 |
