3 2 | x | + | x | + | ( | ( | 3 2 | x | + | x | ) | ÷ | 2 | − | 280 | ) | = | 5000 |
Left side of the equation = | 5 2 | x | + | ( | ( | 3 2 | x | + | x | ) | ÷ | 2 | − | 280 | ) |
5 2 | x | + | ( | ( | 3 2 | x | + | x | ) | ÷ | 2 | − | 280 | ) | = | 5000 |
Left side of the equation = | 5 2 | x | + | ( | 3 2 | x | + | x | ) | ÷ | 2 | − | 280 |
= | 5 2 | x | + | 3 2 | x | × | 1 2 | + | x | × | 1 2 | − | 280 |
= | 5 2 | x | + | 3 4 | x | + | x | × | 1 2 | − | 280 |
= | 15 4 | x | − | 280 |
15 4 | x | − | 280 | = | 5000 |
15 4 | x | = | 5000 | + | 280 |
15 4 | x | = | 5280 |
x | = | 5280 | ÷ | 15 4 |
= | 5280 | × | 4 15 |
= | 352 | × | 4 |
x | = | 1408 |
