multiply the first number with the ones inside of the parenthesis and remember same signs equals positive and different signs equals negative  -6t +6- 8t+4= t +4-5t.

now you put all the numbers with the letter T together and resolve the sum: -6t -8t +10= t- 5t +4.

now you have -14t +10= -4t +4 because you sum the same signs and substract the different signs. remember the biggest number is negative(-5) so the result is negative(-4).

-14t+4t= -10+4 here you moved -4t and you changed it to positive and +10 to negative. you always do this when you change numbers to the other side.    

-10t=-6 here the biggest number is - 14 so is - 10.  the biggest number is -10 so is -6. both are subtractions.  

-10t=-6 divide both between -10 to know the final answer.

t= 6/10 or -6/-10. negative and negative is positive.
