( | 54 5 | y | + | 1100 | × | 141 10 | ) | ÷ | ( | y | + | 1100 | ) | = | 12 |
Multiply both sides of the equation by: | ( | y | + | 1100 | ) |
( | 54 5 | y | + | 1100 | × | 141 10 | ) | = | 12 | ( | y | + | 1100 | ) |
54 5 | y | + | 1100 | × | 141 10 | = | 12 | ( | y | + | 1100 | ) |
54 5 | y | + | 1100 | × | 141 10 | = | 12 | y | + | 12 | × | 1100 |
54 5 | y | + | 15510 | = | 12 | y | + | 13200 |
54 5 | y | − | 12 | y | = | 13200 | − | 15510 |
- | 6 5 | y | = | 13200 | − | 15510 |
- | 6 5 | y | = | - | 2310 |
2310 | = | 6 5 | y |
6 5 | y | = | 2310 |
y | = | 2310 | ÷ | 6 5 |
= | 2310 | × | 5 6 |
= | 385 | × | 5 |
y | = | 1925 |
