(x-8)+(8x+4)=8x-(2-x)

解答

(x - 8) + (8 x + 4) = 8 x - (2 - x)

解答

无解

求解步骤

(x - 8) + (8 x + 4) = 8 x - (2 - x)

去除括号:

(a) = a

x - 8 + 8 x + 4 = 8 x - (2 - x)

对同类项分组

x + 8 x - 8 + 4 = 8 x - (2 - x)

同类项相加:

x + 8 x = 9 x

9 x - 8 + 4 = 8 x - (2 - x)

数字相加/相减:

- 8 + 4 = - 4

9 x - 4 = 8 x - (2 - x)

展开

8 x - (2 - x) : 9 x - 2

9 x - 4 = 9 x - 2

将

4

到右边

9 x = 9 x + 2

将

9 x

solvefor a,8(7+14a)=11(2b-1)

so l v e f or a, 8 (7 + 14 a) = 11 (2 b - 1)

solvefor x,2x+4y=-3

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

f (4) = 3 y

H=(-2)/5+3/2-4/6

H = \frac{- 2}{5} + \frac{3}{2} - \frac{4}{6}

solvefor z,-p*(51+z)=dz+84

so l v e f or z, - p \cdot (51 + z) = d z + 84
