32+T_{3}=12\times 3+2\times 3^{2}
Add 14 and 18 to get 32.
32+T_{3}=36+2\times 3^{2}
Multiply 12 and 3 to get 36.
32+T_{3}=36+2\times 9
Calculate 3 to the power of 2 and get 9.
32+T_{3}=36+18
Multiply 2 and 9 to get 18.
32+T_{3}=54
Add 36 and 18 to get 54.
T_{3}=54-32
Subtract 32 from both sides.
T_{3}=22
Subtract 32 from 54 to get 22.
