( | a | × | 20 100 | + | ( | a | × | 20 100 | + | a | ) | ) | × | 20 100 | = | 171000 |
Left side of the equation = | a | × | 20 100 | × | 20 100 | + | ( | a | × | 20 100 | + | a | ) | × | 20 100 |
= | a | × | 1 25 | + | ( | a | × | 20 100 | + | a | ) | × | 20 100 |
= | 1 25 | a | + | a | × | 20 100 | × | 20 100 | + | a | × | 20 100 |
= | 1 25 | a | + | a | × | 1 25 | + | a | × | 20 100 |
= | 7 25 | a |
7 25 | a | = | 171000 |
a | = | 171000 | ÷ | 7 25 |
= | 171000 | × | 25 7 |
a | = | 4275000 7 |
a | = | 610714.285714 |
