427 100 | = | x | × | 150 | × | 150 | − | 300 | x | + | 15 4 |
Right side of the equation = | x | × | 22500 | − | 300 | x | + | 15 4 |
= | 22200 | x | + | 15 4 |
427 100 | = | 22200 | x | + | 15 4 |
- | 22200 | x | = | 15 4 | − | 427 100 |
- | 22200 | x | = | - | 13 25 |
13 25 | = | 22200 | x |
22200 | x | = | 13 25 |
x | = | 13 25 | ÷ | 22200 |
= | 13 25 | × | 1 22200 |
x | = | 13 555000 |
x | = | 0.000023 |
