( | 3 | x | + | 10 | ) | × | 42 | x | ÷ | ( | 7 | x | + | 10 | ) | − | 18 | x | = | 32 |
Multiply both sides of the equation by: | ( | 7 | x | + | 10 | ) |
( | 3 | x | + | 10 | ) | × | 42 | x | − | 18 | x | ( | 7 | x | + | 10 | ) | = | 32 | ( | 7 | x | + | 10 | ) |
3 | x | × | 42 | x | + | 10 | × | 42 | x | − | 18 | x | ( | 7 | x | + | 10 | ) | = | 32 | ( | 7 | x | + | 10 | ) |
3 | x | × | 42 | x | + | 10 | × | 42 | x | − | 18 | x | ( | 7 | x | + | 10 | ) | = | 32 | × | 7 | x | + | 32 | × | 10 |
126 | x | x | + | 420 | x | − | 18 | x | ( | 7 | x | + | 10 | ) | = | 224 | x | + | 320 |
126 | x | x | + | 420 | x | − | 18 | x | × | 7 | x | − | 18 | x | × | 10 | = | 224 | x | + | 320 |
126 | x | x | + | 420 | x | − | 126 | x | x | − | 180 | x | = | 224 | x | + | 320 |
126 | x | x | + | 240 | x | − | 126 | x | x | = | 224 | x | + | 320 |
