Question

solve ; (12x/(3x-3))+(1/3)=4/(x-1)

Answer 1

12x/3x-3 + 1/3
Multiply the right hand term by x-1/x-1.
12x/(3x-3) + (x-1)/(3x-3)=4/(x-1)
Now multiply the right hand side by 3/3
12x/(3x-3)+(x-1)/(3x-3)=12/(3x-3)
(13x-1)/(3x-3) -= 12/(3x-3)

Multiply both sides by 3x - 3
13x - 1 = 12
13x = 12 + 1
13x = 13
x = 1
