7 | ÷ | 18 | × | x | = | 11 | ÷ | 18 | × | x | − | 78 |
Left side of the equation = | 7 18 | x |
7 18 | x | = | 11 | ÷ | 18 | × | x | − | 78 |
Right side of the equation = | 11 18 | x | − | 78 |
7 18 | x | = | 11 18 | x | − | 78 |
7 18 | x | − | 11 18 | x | = | - | 78 |
- | 2 9 | x | = | - | 78 |
78 | = | 2 9 | x |
2 9 | x | = | 78 |
x | = | 78 | ÷ | 2 9 |
= | 78 | × | 9 2 |
= | 39 | × | 9 |
x | = | 351 |
