2 | ( | 9 | − | 2 | X | × | 1 | ) | = | 3 | ( | 11 | − | 2 | X | × | 2 | ) |
Left side of the equation = | 2 | × | 9 | − | 2 | × | 2 | X | × | 1 |
= | 18 | − | 4 | X |
18 | − | 4 | X | = | 3 | ( | 11 | − | 2 | X | × | 2 | ) |
Right side of the equation = | 3 | × | 11 | − | 3 | × | 2 | X | × | 2 |
= | 33 | − | 12 | X |
18 | − | 4 | X | = | 33 | − | 12 | X |
- | 4 | X | + | 12 | X | = | 33 | − | 18 |
8 | X | = | 33 | − | 18 |
8 | X | = | 15 |
X | = | 15 | ÷ | 8 |
= | 15 | × | 1 8 |
X | = | 15 8 |
X | = | 1.875 |
