14 | + | 25 100 | x | − | 2 | = | ( | 1 | − | 25 100 | ) | x | + | 2 |
Left side of the equation = | 12 | + | 25 100 | x |
12 | + | 25 100 | x | = | ( | 1 | − | 25 100 | ) | x | + | 2 |
Right side of the equation = | 1 | x | − | 25 100 | x | + | 2 |
= | 3 4 | x | + | 2 |
12 | + | 25 100 | x | = | 3 4 | x | + | 2 |
25 100 | x | − | 3 4 | x | = | 2 | − | 12 |
- | 1 2 | x | = | 2 | − | 12 |
- | 1 2 | x | = | - | 10 |
10 | = | 1 2 | x |
1 2 | x | = | 10 |
x | = | 10 | ÷ | 1 2 |
= | 10 | × | 2 |
x | = | 20 |
