4(1/2 x-1/2)= 1/2 (8x+6)

解答

4 (\frac{1}{2} x - \frac{1}{2}) = \frac{1}{2} (8 x + 6)

解答

x = - \frac{5}{2}

+1

十进制

x = - 2.5

求解步骤

4 (\frac{1}{2} x - \frac{1}{2}) = \frac{1}{2} (8 x + 6)

展开

4 (\frac{1}{2} x - \frac{1}{2}) : 2 x - 2

展开

\frac{1}{2} (8 x + 6) : 4 x + 3

2 x - 2 = 4 x + 3

将

2

到右边

2 x = 4 x + 5

将

4 x

para o lado esquerdo

- 2 x = 5

两边除以

- 2

x = - \frac{5}{2}

4(x-2)-2/3 (3x+1)=5-2x

4 (x - 2) - \frac{2}{3} (3 x + 1) = 5 - 2 x

solvefor y,2y+4=x

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

solvefor n,n(t)=6\sqrt[3]{t^2}+3t+25000

so l v e f or n, n (t) = 6 3 t^{2} + 3 t + 25000

(x-3)(x/3+7/2)=(x/3-3)(x-4/3)

(x - 3) (\frac{x}{3} + \frac{7}{2}) = (\frac{x}{3} - 3) (x - \frac{4}{3})

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