179 500 | × | 100 | + | 397 500 | X | = | ( | 100 | + | X | ) | × | 81 200 |
Left side of the equation = | 179 5 | + | 397 500 | X |
179 5 | + | 397 500 | X | = | ( | 100 | + | X | ) | × | 81 200 |
Right side of the equation = | 100 | × | 81 200 | + | X | × | 81 200 |
= | 81 2 | + | X | × | 81 200 |
179 5 | + | 397 500 | X | = | 81 2 | + | 81 200 | X |
397 500 | X | − | 81 200 | X | = | 81 2 | − | 179 5 |
389 1000 | X | = | 81 2 | − | 179 5 |
389 1000 | X | = | 47 10 |
X | = | 47 10 | ÷ | 389 1000 |
= | 47 10 | × | 1000 389 |
= | 47 | × | 100 389 |
X | = | 4700 389 |
X | = | 12.082262 |
