Respuesta :

-7=t.
you multiply t and negative 7 so it would be 3t-21=6t. Then you would subtract 3t which would equal -21=3t. Finally you divide 3 on both sides and your answer would be -7=t.

I got t=-7. I found my answer by first distributing 3 to whatever was in the parenthesis, and I rewrote the equation giving me (3t-21)=6t. Then, I subtracted 3t from both sides of the equation giving me - 21=3t. Divide both sides by 3 and you will get -7. Hope this helped :) Have a blessed day!
