solvefor x,f(x-2)=2x-1

解答

求解

x, f (x - 2) = 2 x - 1

解答

x = \frac{- 1 + 2 f}{f - 2}; f \neq = 2

求解步骤

f (x - 2) = 2 x - 1

展开

f (x - 2) : x f - 2 f

x f - 2 f = 2 x - 1

将

2 f

到右边

x f = 2 x - 1 + 2 f

将

2 x

para o lado esquerdo

x f - 2 x = - 1 + 2 f

分解

x f - 2 x : x (f - 2)

x (f - 2) = - 1 + 2 f

两边除以

f - 2; f \neq = 2

x = \frac{- 1 + 2 f}{f - 2}; f \neq = 2

4 t = 5 + 3

solvefor m,x-1/(x^2)+3x+2= m/x+2+n/x+1

so l v e f or m, x - \frac{1}{x ^{2}} + 3 x + 2 = \frac{m}{x} + 2 + \frac{n}{x} + 1

solvefor x,2x+y=z

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

solvefor x,f=3-9xf(5)

so l v e f or x, f = 3 - 9 x f (5)

solvefor a,q=acsc(b)0

so l v e f or a, q = a csc (b) 0
