Question 56427
Next time, could you add parenthesis to help me better understand what you are implying. I can only guess.
13/(x - 1) = 4/(x + 2)
13(x - 1)(x + 2)/(x - 1) = 4(x - 1)(x + 2)/(x + 2) Since you have an EQuation, you can multiply throughout.
13(x + 2) = 4(x - 1)
13x + 26 = 4x - 4
9x = -30
x = -10/3
