( | X | − | 3 | ) | + | ( | X | + | 3 | ) | + | X | ÷ | 3 | + | 3 | X | = | 48 |
Left side of the equation = | ( | X | − | 3 | ) | + | ( | X | + | 3 | ) | + | 10 3 | X |
( | X | − | 3 | ) | + | ( | X | + | 3 | ) | + | 10 3 | X | = | 48 |
Left side of the equation = | X | − | 3 | + | ( | X | + | 3 | ) | + | 10 3 | X |
= | 13 3 | X | − | 3 | + | ( | X | + | 3 | ) |
= | 13 3 | X | − | 3 | + | X | + | 3 |
= | 16 3 | X | − | 0 |
16 3 | X | − | 0 | = | 48 |
X | = | 48 | ÷ | 16 3 |
= | 48 | × | 3 16 |
= | 3 | × | 3 |
X | = | 9 |
