3 25 | × | 20 | + | 3 25 | × | 3 4 | x | − | 15 | = | 1 10 | x |
Left side of the equation = | 12 5 | + | 9 100 | x | − | 15 |
= | - | 63 5 | + | 9 100 | x |
- | 63 5 | + | 9 100 | x | = | 1 10 | x |
9 100 | x | − | 1 10 | x | = | 63 5 |
- | 1 100 | x | = | 63 5 |
- | 63 5 | = | 1 100 | x |
1 100 | x | = | - | 63 5 |
x | = | - | 63 5 | ÷ | 1 100 |
= | - | 63 5 | × | 100 |
= | - | 63 | × | 20 |
x | = | - | 1260 |
