7 10 | × | 40 | x | = | 4 5 | × | 40 | ( | x | − | 6 | ) |
Left side of the equation = | 28 | x |
28 | x | = | 4 5 | × | 40 | ( | x | − | 6 | ) |
Right side of the equation = | 32 | ( | x | − | 6 | ) |
28 | x | = | 32 | ( | x | − | 6 | ) |
Right side of the equation = | 32 | x | − | 32 | × | 6 |
= | 32 | x | − | 192 |
28 | x | = | 32 | x | − | 192 |
28 | x | − | 32 | x | = | - | 192 |
- | 4 | x | = | - | 192 |
192 | = | 4 | x |
4 | x | = | 192 |
x | = | 192 | ÷ | 4 |
= | 192 | × | 1 4 |
= | 48 | × | 1 |
x | = | 48 |
