720 | × | 1920 | ÷ | x | = | 300 | − | ( | x | − | 6240 | ) | × | 1920 | ÷ | x |
Multiply both sides of the equation by: | x |
720 | × | 1920 | = | 300 | x | − | ( | x | − | 6240 | ) | × | 1920 | ÷ | 1 | × | 1 |
720 | × | 1920 | = | 300 | x | − | x | × | 1920 | ÷ | 1 | × | 1 | + | 6240 | × | 1920 | ÷ | 1 | × | 1 |
1382400 | = | 300 | x | − | x | × | 1920 | + | 11980800 |
1382400 | = | - | 1620 | x | + | 11980800 |
1620 | x | = | 11980800 | − | 1382400 |
1620 | x | = | 10598400 |
x | = | 10598400 | ÷ | 1620 |
= | 10598400 | × | 1 1620 |
= | 58880 | × | 1 9 |
x | = | 58880 9 |
x | = | 6542.222222 |
