你好~

3 × 5.067 × [ 2040000 × 0.003(43.5 - X)/X ]
= 3 × 5.067 × 2040000 × 0.003 × (43.5 - X) / X
= 3 × 5.067 × 2040000 × 0.003 × (43.5 - X) / X
= 93030.12 × (43.5 - X) / X
= (93030.12 × 43.5 - 93030.12 × X) / X
= (4046810.22 - 93030.12X) / X
= 4046810.22/X - 93030.12X/X
= 4046810.22/X - 93030.12
≈ 4046810/X - 93030

什麼叫 "方程式"?
沒有等號怎會是方程式?


什麼叫 "方程式的解"?
一個未知數的方程式的解不應含有未知數.
