300 | × | 15 | = | 75 | × | 5 | + | 10 | x | + | 235 | × | 15 |
Left side of the equation = | 4500 |
4500 | = | 75 | × | 5 | + | 10 | x | + | 235 | × | 15 |
Right side of the equation = | 375 | + | 10 | x | + | 3525 |
= | 3900 | + | 10 | x |
4500 | = | 3900 | + | 10 | x |
- | 10 | x | = | 3900 | − | 4500 |
- | 10 | x | = | - | 600 |
600 | = | 10 | x |
10 | x | = | 600 |
x | = | 600 | ÷ | 10 |
= | 600 | × | 1 10 |
= | 60 | × | 1 |
x | = | 60 |
