1500 | × | 88 100 | + | X | = | ( | 1500 | + | X | ) | × | 92 100 |
Left side of the equation = | 1320 | + | X |
1320 | + | X | = | ( | 1500 | + | X | ) | × | 92 100 |
Right side of the equation = | 1500 | × | 92 100 | + | X | × | 92 100 |
= | 1380 | + | X | × | 92 100 |
1320 | + | X | = | 1380 | + | 92 100 | X |
X | − | 92 100 | X | = | 1380 | − | 1320 |
2 25 | X | = | 1380 | − | 1320 |
2 25 | X | = | 60 |
X | = | 60 | ÷ | 2 25 |
= | 60 | × | 25 2 |
= | 30 | × | 25 |
X | = | 750 |
