Solve for x: k=3x+2/x-1
Anna11 [10]

Answer:

x = (2+k)/(k-3)

Step-by-step explanation:

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

First just multiply both sides by (x-1)

(x-1)k = 3x+2

kx - k = 3x+2

Add k both sides and Subtract 3x both sides to get:

kx - 3x = 2+k

Take x out since it's common

x(k-3) = 2+k

Multiply both sides by (k-3)

x = (2+k)/(k-3)

Hope this helps!
