( | 3 | X | + | 39 | ) | + | ( | 3 | X | + | 50 | ) | + | 25 | = | 3 | X | − | 26 |
Left side of the equation = | 3 | X | + | 39 | + | ( | 3 | X | + | 50 | ) | + | 25 |
= | 3 | X | + | 64 | + | ( | 3 | X | + | 50 | ) |
= | 3 | X | + | 64 | + | 3 | X | + | 50 |
= | 6 | X | + | 114 |
6 | X | + | 114 | = | 3 | X | − | 26 |
6 | X | − | 3 | X | = | - | 26 | − | 114 |
3 | X | = | - | 26 | − | 114 |
3 | X | = | - | 140 |
X | = | - | 140 | ÷ | 3 |
= | - | 140 | × | 1 3 |
X | = | - | 140 3 |
X | = | - 46.666667 |
