75 | ÷ | x | − | 75 | ÷ | ( | 5 4 | x | ) | = | 30 | ÷ | 60 |
Multiply both sides of the equation by: | x |
75 | − | 75 | ÷ | ( | 5 4 | × | 1 | ) | × | 1 | = | 30 | ÷ | 60 | × | x |
Multiply both sides of the equation by: | ( | 5 4 | × | 1 | ) |
75 | ( | 5 4 | × | 1 | ) | − | 75 | × | 1 | = | 30 | ÷ | 60 | × | x | ( | 5 4 | × | 1 | ) |
75 | × | 5 4 | × | 1 | − | 75 | × | 1 | = | 30 | ÷ | 60 | × | x | ( | 5 4 | × | 1 | ) |
75 | × | 5 4 | × | 1 | − | 75 | × | 1 | = | 30 | ÷ | 60 | × | x | × | 5 4 | × | 1 |
375 4 | − | 75 | = | 5 8 | x |
75 4 | = | 5 8 | x |
- | 5 8 | x | = | - | 75 4 |
75 4 | = | 5 8 | x |
5 8 | x | = | 75 4 |
x | = | 75 4 | ÷ | 5 8 |
= | 75 4 | × | 8 5 |
= | 15 | × | 2 |
