3 50 | = | ( | ( | x | − | 99 | ) | ÷ | 99 | ) | x | ( | 360 | ÷ | 180 | ) |
Right side of the equation = | ( | x | − | 99 | ) | ÷ | 99 | × | x | ( | 360 | ÷ | 180 | ) |
= | x | × | 1 99 | x | ( | 360 | ÷ | 180 | ) | − | 99 | × | 1 99 | x | ( | 360 | ÷ | 180 | ) |
= | x | × | 1 99 | x | ( | 360 | ÷ | 180 | ) | − | 1 | x | ( | 360 | ÷ | 180 | ) |
= | x | × | 1 99 | x | × | 360 | ÷ | 180 | − | 1 | x | ( | 360 | ÷ | 180 | ) |
= | x | × | 2 99 | x | − | 1 | x | ( | 360 | ÷ | 180 | ) |
= | x | × | 2 99 | x | − | 1 | x | × | 360 | ÷ | 180 |
= | x | × | 2 99 | x | − | 2 | x |
3 50 | = | x | × | 2 99 | x | − | 2 | x |
