How to isolate t in 3tx-5x=(t+2)(t-3)-t^2-1/x

t = (5x² - 6x - 1)/(3x² - 5x²)

Step-by-step explanation:

               3tx - 5x = (t + 2)(t - 3) - t² -

               3tx - 5x = t² - t - 6 - t² -

               3tx - 5x = - t - 6 -

            3tx² - 5x² = -tx - 6x - 1

            +tx + 5x²    +tx + 5x²    

             3tx² + tx =  5x² - 6x - 1

        t(3x² - 5x²)  = 5x² - 6x - 1

      ÷ (3x² - 5x²)  ÷ (3x² - 5x²)

                       t = (5x² - 6x - 1)/(3x² - 5x²)

25 questions , because they start with 100.  

350-100=250 .  

. 250/10=25

step-by-step explanation:

first take off 100, then what x 10 = 250? that is your answer. (25)
