- | 4082750 | + | 300000 | + | a | − | a | × | 10 100 | ÷ | 4 | − | 450000 | = | 30000 |
Left side of the equation = | - | 4082750 | + | 300000 | + | a | − | a | × | 1 40 | − | 450000 |
= | - | 4232750 | + | 39 40 | a |
- | 4232750 | + | 39 40 | a | = | 30000 |
39 40 | a | = | 30000 | + | 4232750 |
39 40 | a | = | 4262750 |
a | = | 4262750 | ÷ | 39 40 |
= | 4262750 | × | 40 39 |
a | = | 170510000 39 |
a | = | 4372051.282051 |
