( | x | − | 899 1000 | ) | × | 400 | − | 1 10 | = | 1 |
Left side of the equation = | x | × | 400 | − | 899 1000 | × | 400 | − | 1 10 |
= | x | × | 400 | − | 1798 5 | − | 1 10 |
= | 400 | x | − | 3597 10 |
400 | x | − | 3597 10 | = | 1 |
400 | x | = | 1 | + | 3597 10 |
400 | x | = | 3607 10 |
x | = | 3607 10 | ÷ | 400 |
= | 3607 10 | × | 1 400 |
x | = | 3607 4000 |
x | = | 0.90175 |
