Question

-4(t-3)-(t+6)=9
i got t=-3 but when i check it dont check out

Answer 1

let's try
\[\implies -4(-3 - 3) - (-3 + 6) = 9\]
\[\implies -4(-6) - (3) = 9\]
\[\implies 24 - 3 = 9\]
\[\implies 21 \ne 9\]

Answer 2

let's try resolving
\[-4(t - 3) - (t + 6) = 9\]
distribute..
\[\implies -4t + 12 - t - 6 = 9\]
combine like terms...
\[\implies -5t + 6 = 9\]
subtract 6 from both sides...
\[\implies -5t = 3\]
do you see it now?

Answer 3

oh i had subtracted 6 from 6 and added 6 to the 9 the first time

Answer 4
