( | 1000 | + | 1500 | ) | x | + | ( | 300 | + | 100 | ) | x | × | 3 | = | 24000 |
Left side of the equation = | 1000 | x | + | 1500 | x | + | ( | 300 | + | 100 | ) | x | × | 3 |
= | 2500 | x | + | ( | 300 | + | 100 | ) | x | × | 3 |
= | 2500 | x | + | 300 | x | × | 3 | + | 100 | x | × | 3 |
= | 2500 | x | + | 900 | x | + | 300 | x |
= | 3700 | x |
3700 | x | = | 24000 |
x | = | 24000 | ÷ | 3700 |
= | 24000 | × | 1 3700 |
= | 240 | × | 1 37 |
x | = | 240 37 |
x | = | 6.486486 |
