7x-1=8x-14

解答

7 x - 1 = 8 x - 14

x = 13

求解步骤

7 x - 1 = 8 x - 14

将

1

到右边

7 x = 8 x - 13

将

8 x

para o lado esquerdo

- x = - 13

两边除以

- 1

x = 13

10 x - 4.5 + 3 x = 12 x - 1.1

- 6 (v + 1) + 8 v = 2 (v - 3)

x \leq 1 and x \geq 3

f a c t or 2 w^{2} + 3 w - 35

s im pl i f y \frac{1000 0 ^{2} \cdot 1.5 \cdot 1 0 ^{- 12}}{2.4}
