( | 3600 | + | x | ) | ÷ | ( | 13000 | + | x | ) | = | 1 4 |
Multiply both sides of the equation by: | ( | 13000 | + | x | ) |
( | 3600 | + | x | ) | = | 1 4 | ( | 13000 | + | x | ) |
3600 | + | x | = | 1 4 | ( | 13000 | + | x | ) |
3600 | + | x | = | 1 4 | × | 13000 | + | 1 4 | x |
3600 | + | x | = | 3250 | + | 1 4 | x |
x | − | 1 4 | x | = | 3250 | − | 3600 |
3 4 | x | = | 3250 | − | 3600 |
3 4 | x | = | - | 350 |
x | = | - | 350 | ÷ | 3 4 |
= | - | 350 | × | 4 3 |
x | = | - | 1400 3 |
x | = | - 466.666667 |
