解答

x = \frac{863}{41}

+1

十进制

x = 21.04878 \dots

求解步骤

x + 69 + x + 49 + x + 34 x + 4 x = 981

对同类项分组

x + x + x + 34 x + 4 x + 69 + 49 = 981

同类项相加:

x + x + x + 34 x + 4 x = 41 x

41 x + 69 + 49 = 981

数字相加:

69 + 49 = 118

41 x + 118 = 981

将

118

到右边

41 x = 863

两边除以

41

x = \frac{863}{41}

流行的例子

((2x-a))/b =((2x-b))/a

\frac{( 2 x - a )}{b} = \frac{( 2 x - b )}{a}

2 x + 2 b = a

4 = 0.3 q + 2

solvefor x,3x+2y=29

so l v e f or x, 3 x + 2 y = 29

10 (1.5)^{3} x = 80
