solvefor x,m^2x+1=m(x+1)

解答

求解

x, m^{2} x + 1 = m (x + 1)

解答

x = \frac{1}{m}; m \neq = 0, m \neq = 1

求解步骤

m^{2} x + 1 = m (x + 1)

展开

m (x + 1) : m x + m

m^{2} x + 1 = m x + m

将

1

到右边

m^{2} x = m x + m - 1

将

m x

para o lado esquerdo

m^{2} x - m x = m - 1

分解

m^{2} x - m x : m x (m - 1)

m x (m - 1) = m - 1

两边除以

m (m - 1); m \neq = 0, m \neq = 1

x = \frac{1}{m}; m \neq = 0, m \neq = 1

solvefor x,-3x+y=18

so l v e f or x, - 3 x + y = 18

2.7927=(1-x)*0.4231+8.4739x

2.7927 = (1 - x) \cdot 0.4231 + 8.4739 x

24=a_{0}(0+3)(0+4)

24 = a_{0} (0 + 3) (0 + 4)

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

\frac{- 3 x + 4}{2} = \frac{1}{3}

- 10 = - x + 3
