( | ( | 0 | + | a | + | 10000 | ) | − | 5000 | ) | × | 3 100 | = | 0 | + | a |
Left side of the equation = | ( | 0 | + | a | + | 10000 | ) | × | 3 100 | − | 5000 | × | 3 100 |
= | ( | 0 | + | a | + | 10000 | ) | × | 3 100 | − | 150 |
= | 0 | × | 3 100 | + | a | × | 3 100 | + | 10000 | × | 3 100 | − | 150 |
= | 0 | + | a | × | 3 100 | + | 300 | − | 150 |
= | 150 | + | 3 100 | a |
150 | + | 3 100 | a | = | 0 | + | a |
3 100 | a | − | a | = | - | 150 |
- | 97 100 | a | = | - | 150 |
150 | = | 97 100 | a |
97 100 | a | = | 150 |
a | = | 150 | ÷ | 97 100 |
= | 150 | × | 100 97 |
a | = | 15000 97 |
a | = | 154.639175 |
