100 | × | 22 | + | 100 | × | 102 5 | + | x | × | 82 | = | ( | 100 | + | x | ) | × | 25 |
Left side of the equation = | 2200 | + | 2040 | + | x | × | 82 |
= | 4240 | + | 82 | x |
4240 | + | 82 | x | = | ( | 100 | + | x | ) | × | 25 |
Right side of the equation = | 100 | × | 25 | + | x | × | 25 |
= | 2500 | + | x | × | 25 |
4240 | + | 82 | x | = | 2500 | + | 25 | x |
82 | x | − | 25 | x | = | 2500 | − | 4240 |
57 | x | = | 2500 | − | 4240 |
57 | x | = | - | 1740 |
x | = | - | 1740 | ÷ | 57 |
= | - | 1740 | × | 1 57 |
= | - | 580 | × | 1 19 |
x | = | - | 580 19 |
