( | 42309 1000 | + | x | ) | × | 31 20 | = | 42309 1000 | + | 36959 500 | − | x |
Left side of the equation = | 42309 1000 | × | 31 20 | + | x | × | 31 20 |
= | 1311579 20000 | + | x | × | 31 20 |
1311579 20000 | + | 31 20 | x | = | 42309 1000 | + | 36959 500 | − | x |
Right side of the equation = | 116227 1000 | − | x |
1311579 20000 | + | 31 20 | x | = | 116227 1000 | − | x |
31 20 | x | + | x | = | 116227 1000 | − | 1311579 20000 |
51 20 | x | = | 116227 1000 | − | 1311579 20000 |
51 20 | x | = | 1012961 20000 |
x | = | 1012961 20000 | ÷ | 51 20 |
= | 1012961 20000 | × | 20 51 |
= | 1012961 1000 | × | 1 51 |
