3 | N | × | 129 | × | 1 5 | + | 400 | = | N | × | 129 | × | 1 2 | − | 400 |
Left side of the equation = | 387 5 | N | + | 400 |
387 5 | N | + | 400 | = | N | × | 129 | × | 1 2 | − | 400 |
Right side of the equation = | N | × | 129 2 | − | 400 |
387 5 | N | + | 400 | = | 129 2 | N | − | 400 |
387 5 | N | − | 129 2 | N | = | - | 400 | − | 400 |
129 10 | N | = | - | 400 | − | 400 |
129 10 | N | = | - | 800 |
N | = | - | 800 | ÷ | 129 10 |
= | - | 800 | × | 10 129 |
N | = | - | 8000 129 |
N | = | - 62.015504 |
