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

解答

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

解答

x = \frac{9}{2}

+1

十进制

x = 4.5

求解步骤

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

乘开

2 (x - 3) : 2 x - 6

5 x + 2 x - 6 = 3 (4 + x)

同类项相加:

5 x + 2 x = 7 x

7 x - 6 = 3 (4 + x)

展开

3 (4 + x) : 12 + 3 x

7 x - 6 = 12 + 3 x

将

6

到右边

7 x = 3 x + 18

将

3 x

para o lado esquerdo

4 x = 18

两边除以

4

((3x-4)}{5+6}=\frac{25x-(x+4))/2

\frac{( 3 x - 4 )}{5 + 6} = \frac{25 x - ( x + 4 )}{2}

solvefor x,y+5= 2/2*(x-3)

so l v e f or x, y + 5 = \frac{2}{2} \cdot (x - 3)

r^1=[(1.1)(2.2)(3.3)(4.4)]

r^{1} = [(1.1) (2.2) (3.3) (4.4)]

2x=9,p(x)=0.62,n=1

2 x = 9, p (x) = 0.62, n = 1

x/(1.6+2.8)=8.8

\frac{x}{1.6 + 2.8} = 8.8
