8t+4t-8=-2-6\left(2t+9\right)
Use the distributive property to multiply 4 by t-2.
12t-8=-2-6\left(2t+9\right)
Combine 8t and 4t to get 12t.
12t-8=-2-12t-54
Use the distributive property to multiply -6 by 2t+9.
12t-8=-56-12t
Subtract 54 from -2 to get -56.
12t-8+12t=-56
Add 12t to both sides.
24t-8=-56
Combine 12t and 12t to get 24t.
24t=-56+8
Add 8 to both sides.
24t=-48
Add -56 and 8 to get -48.
t=\frac{-48}{24}
Divide both sides by 24.
t=-2
Divide -48 by 24 to get -2.
