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

解答

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

解答

x = 2

求解步骤

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

乘开

- 3 (2 x - 1) : - 6 x + 3

5 x - 6 x + 3 = 1 - 4 (x - 2)

同类项相加:

5 x - 6 x = - x

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

展开

1 - 4 (x - 2) : - 4 x + 9

- x + 3 = - 4 x + 9

将

5/6 y= 1/2 y+2/3

\frac{5}{6} y = \frac{1}{2} y + \frac{2}{3}

solvefor x,4y-2x=-8

so l v e f or x, 4 y - 2 x = - 8

5 x - 6 = 12

x (x + 5) - 8 = x^{2} + 8

solvefor t,\at+b(t-b)=c

so l v e f or t, at + b (t - b) = c
