433 | + | ( | 433 | − | 100 | ) | ( | a | × | 1 200 | ) | = | 75601 100 |
Left side of the equation = | 433 | + | 433 | ( | a | × | 1 200 | ) | − | 100 | ( | a | × | 1 200 | ) |
= | 433 | + | 433 | a | × | 1 200 | − | 100 | ( | a | × | 1 200 | ) |
= | 433 | + | 433 200 | a | − | 100 | ( | a | × | 1 200 | ) |
= | 433 | + | 433 200 | a | − | 100 | a | × | 1 200 |
= | 433 | + | 433 200 | a | − | 1 2 | a |
= | 433 | + | 333 200 | a |
433 | + | 333 200 | a | = | 75601 100 |
333 200 | a | = | 75601 100 | − | 433 |
333 200 | a | = | 32301 100 |
a | = | 32301 100 | ÷ | 333 200 |
= | 32301 100 | × | 200 333 |
= | 97 | × | 2 |
a | = | 194 |
