solvefor d,3-1/2 d= 3/2 d+4-d

解答

求解

d, 3 - \frac{1}{2} d = \frac{3}{2} d + 4 - d

d = - 1

求解步骤

3 - \frac{1}{2} d = \frac{3}{2} d + 4 - d

将

3

到右边

- \frac{1}{2} d = \frac{1}{2} d + 1

将

\frac{1}{2} d

para o lado esquerdo

- d = 1

两边除以

- 1

d = - 1

so l v e f or g, 3 = \frac{g}{- 4 - 5}

so l v e f or x, 4 (x - 2) + 5 x = 2 (3 x - 8)

f a c t or 3 x - 5 x

q u a d r a t i c f or m u l a x^{2} - 3 x = 10

s im pl i f y \frac{5 x}{12}
