solvefor x,ax+b=3(x-a)

解答

求解

x, a x + b = 3 (x - a)

解答

x = \frac{- 3 a - b}{a - 3}; a \neq = 3

求解步骤

a x + b = 3 (x - a)

展开

3 (x - a) : 3 x - 3 a

a x + b = 3 x - 3 a

将

b

到右边

a x = 3 x - 3 a - b

将

3 x

para o lado esquerdo

a x - 3 x = - 3 a - b

分解

a x - 3 x : x (a - 3)

x (a - 3) = - 3 a - b

两边除以

a - 3; a \neq = 3

x = \frac{- 3 a - b}{a - 3}; a \neq = 3

3(v+3)+v=2(v-1)+3

3 (v + 3) + v = 2 (v - 1) + 3

4 x - 3 = 3 x + 4

- \frac{x}{9} + 41 = 42

solvefor x, 1/2 y=x-1

so l v e f or x, \frac{1}{2} y = x - 1

solvefor x,x-piy+z^3=2

so l v e f or x, x - π y + z^{3} = 2
