5 | x | ÷ | ( | x | + | 1200 | ) | = | 121 50 |
Multiply both sides of the equation by: | ( | x | + | 1200 | ) |
5 | x | = | 121 50 | ( | x | + | 1200 | ) |
5 | x | = | 121 50 | x | + | 121 50 | × | 1200 |
5 | x | = | 121 50 | x | + | 2904 |
5 | x | − | 121 50 | x | = | 2904 |
129 50 | x | = | 2904 |
x | = | 2904 | ÷ | 129 50 |
= | 2904 | × | 50 129 |
= | 968 | × | 50 43 |
x | = | 48400 43 |
x | = | 1125.581395 |
