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

解答

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

解答

x = \frac{1}{2}

+1

十进制

x = 0.5

求解步骤

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

去除括号:

(a) = a

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

对同类项分组

x + 10 - 2 = 5 - (x - 4)

数字相加/相减:

10 - 2 = 8

x + 8 = 5 - (x - 4)

展开

5 - (x - 4) : - x + 9

x + 8 = - x + 9

将

8

到右边

x = - x + 1

将

5 x - 3 = a - 18

(-4x+1)/2 = 31/2

\frac{- 4 x + 1}{2} = \frac{31}{2}

solvefor b,3b=6c+b-2c+0.5b

so l v e f or b, 3 b = 6 c + b - 2 c + 0.5 b

solvefor x,v_{2}=42

so l v e f or x, v_{2} = 42

8-x/3+10-x/5 =2x-3/7+x/5

8 - \frac{x}{3} + 10 - \frac{x}{5} = 2 x - \frac{3}{7} + \frac{x}{5}
