5(u-2)+6=3(6-2u)

解答

5 (u - 2) + 6 = 3 (6 - 2 u)

解答

u = 2

求解步骤

5 (u - 2) + 6 = 3 (6 - 2 u)

展开

5 (u - 2) + 6 : 5 u - 4

展开

3 (6 - 2 u) : 18 - 6 u

5 u - 4 = 18 - 6 u

将

4

到右边

5 u = - 6 u + 22

将

6 u

para o lado esquerdo

11 u = 22

两边除以

11

u = 2

x = 123 \cdot 1 \cdot (42)

x - 7 = 2 (x + 1)

7*(x-4)^2-3*(x+5)^2=4*(x+1)*(x-1)-2

7 \cdot (x - 4)^{2} - 3 \cdot (x + 5)^{2} = 4 \cdot (x + 1) \cdot (x - 1) - 2

solvefor x,3x-4y-2(2x-7)=0

so l v e f or x, 3 x - 4 y - 2 (2 x - 7) = 0

p(n)=(n+1)(2n-3)

p (n) = (n + 1) (2 n - 3)
