( | 3 | ÷ | 4 | ) | x | + | ( | 3 | ÷ | 5 | ) | ( | 57 | − | x | ) | = | x | ( | 4 | ÷ | 5 | ) |
Left side of the equation = | 3 | ÷ | 4 | × | x | + | ( | 3 | ÷ | 5 | ) | ( | 57 | − | x | ) |
= | 3 4 | x | + | ( | 3 | ÷ | 5 | ) | ( | 57 | − | x | ) |
= | 3 4 | x | + | 3 | ÷ | 5 | × | ( | 57 | − | x | ) |
= | 3 4 | x | + | 3 5 | ( | 57 | − | x | ) |
= | 3 4 | x | + | 3 5 | × | 57 | − | 3 5 | x |
= | 3 4 | x | + | 171 5 | − | 3 5 | x |
= | 3 20 | x | + | 171 5 |
3 20 | x | + | 171 5 | = | x | ( | 4 | ÷ | 5 | ) |
Right side of the equation = | x | × | 4 | ÷ | 5 |
= | x | × | 4 5 |
3 20 | x | + | 171 5 | = | 4 5 | x |
3 20 | x | − | 4 5 | x | = | - | 171 5 |
- | 13 20 | x | = | - | 171 5 |
171 5 | = | 13 20 | x |
13 20 | x | = | 171 5 |
x | = | 171 5 | ÷ | 13 20 |
= | 171 5 | × | 20 13 |
= | 171 | × | 4 13 |
x | = | 684 13 |
x | = | 52.615385 |
