-21+426000x+0.7+867x*52=0

解答

- 21 + 426000 \cdot x + 0.7 + 867 \cdot x \cdot 52 = 0

x = 0.00004 \dots

求解步骤

- 21 + 426000 x + 0.7 + 867 x \cdot 52 = 0

数字相乘:

867 \cdot 52 = 45084

- 21 + 426000 x + 0.7 + 45084 x = 0

对同类项分组

426000 x + 45084 x - 21 + 0.7 = 0

y = 2^{2} + 2 e^{- 3 (2)} - \frac{1}{4 ( 2 )}

x - 2 - \frac{5 x + 7}{6} = \frac{10 - 4 x}{9}

2 x = 2

so l v e f or y, 2 x + 3 y + 4 z = 12

- 21 m = 84
