( | x | − | 1600 | − | 900 | ) | ÷ | 10000 | = | 0 |
Left side of the equation = | x | × | 1 10000 | − | 1600 | × | 1 10000 | − | 900 | × | 1 10000 |
= | x | × | 1 10000 | − | 4 25 | − | 9 100 |
= | 1 10000 | x | − | 1 4 |
1 10000 | x | − | 1 4 | = | 0 |
1 10000 | x | = | 0 | + | 1 4 |
1 10000 | x | = | 1 4 |
x | = | 1 4 | ÷ | 1 10000 |
= | 1 4 | × | 10000 |
= | 1 | × | 2500 |
x | = | 2500 |
