6n+8=1-n

解答

6 n + 8 = 1 - n

n = - 1

求解步骤

6 n + 8 = 1 - n

将

8

到右边

6 n = - n - 7

将

n

para o lado esquerdo

7 n = - 7

两边除以

7

n = - 1

13 x - 1 = 9 x - 13

f a c t or a^{4} - 2 a^{2} b^{2} + b^{4}

\frac{x}{14} \geq 1 - \frac{x}{28}

f a c t or 2 (5 a - 1)^{\frac{3}{4}} + 7 a (5 a - 1)^{- \frac{1}{4}}

2 (- 5 x + 4) + 4 x - 5 = - 3
