3 | ( | 2 | x | − | 7 | ) | − | 15 | x | = | 5 | ( | 4 | + | 3 | x | ) |
Left side of the equation = | 3 | × | 2 | x | − | 3 | × | 7 | − | 15 | x |
= | 6 | x | − | 21 | − | 15 | x |
= | - | 9 | x | − | 21 |
- | 9 | x | − | 21 | = | 5 | ( | 4 | + | 3 | x | ) |
Right side of the equation = | 5 | × | 4 | + | 5 | × | 3 | x |
= | 20 | + | 15 | x |
- | 9 | x | − | 21 | = | 20 | + | 15 | x |
- | 9 | x | − | 15 | x | = | 20 | + | 21 |
- | 24 | x | = | 20 | + | 21 |
- | 24 | x | = | 41 |
- | 41 | = | 24 | x |
24 | x | = | - | 41 |
x | = | - | 41 | ÷ | 24 |
= | - | 41 | × | 1 24 |
x | = | - | 41 24 |
x | = | - 1.708333 |
