20 100 | x | + | ( | 1 | − | x | ) | × | 12 100 | = | 14 100 |
Left side of the equation = | 20 100 | x | + | 1 | × | 12 100 | − | x | × | 12 100 |
= | 20 100 | x | + | 3 25 | − | x | × | 12 100 |
= | 2 25 | x | + | 3 25 |
2 25 | x | + | 3 25 | = | 14 100 |
2 25 | x | = | 14 100 | − | 3 25 |
2 25 | x | = | 1 50 |
x | = | 1 50 | ÷ | 2 25 |
= | 1 50 | × | 25 2 |
= | 1 2 | × | 1 2 |
x | = | 1 4 |
x | = | 0.25 |
