70 | × | 397 50 | + | 239 20 | x | = | ( | 70 | + | x | ) | × | 399 50 |
Left side of the equation = | 2779 5 | + | 239 20 | x |
2779 5 | + | 239 20 | x | = | ( | 70 | + | x | ) | × | 399 50 |
Right side of the equation = | 70 | × | 399 50 | + | x | × | 399 50 |
= | 2793 5 | + | x | × | 399 50 |
2779 5 | + | 239 20 | x | = | 2793 5 | + | 399 50 | x |
239 20 | x | − | 399 50 | x | = | 2793 5 | − | 2779 5 |
397 100 | x | = | 2793 5 | − | 2779 5 |
397 100 | x | = | 14 5 |
x | = | 14 5 | ÷ | 397 100 |
= | 14 5 | × | 100 397 |
= | 14 | × | 20 397 |
x | = | 280 397 |
x | = | 0.70529 |
