( | 120000 | − | 110500 | + | X | ) | ÷ | 120000 | = | 1 10 |
Left side of the equation = | 120000 | × | 1 120000 | − | 110500 | × | 1 120000 | + | X | × | 1 120000 |
= | 1 | − | 221 240 | + | X | × | 1 120000 |
= | 19 240 | + | 1 120000 | X |
19 240 | + | 1 120000 | X | = | 1 10 |
1 120000 | X | = | 1 10 | − | 19 240 |
1 120000 | X | = | 1 48 |
X | = | 1 48 | ÷ | 1 120000 |
= | 1 48 | × | 120000 |
= | 1 | × | 2500 |
X | = | 2500 |
