Answer:
Step-by-step explanation:
[tex]\frac{(3a-b)}{(x-b)}=\frac{1}{(x+1)}\\\\(3a-b)*(x+1)=1*(x-b)\\\\[/tex]
Use FOIL method
3a*x + 3a*1 - b*x -b*1 = x - b
3ax + 3a -bx - b = x -b
3ax - bx -x + 3a - b = -b
x*( 3a - b - 1) + 3a - b = -b
x*( 3a - b - 1) = - b - 3a + b
x*( 3a - b - 1) = -3a
[tex]x=\frac{-3a}{( 3a - b - 1)}[/tex]
