What is the value of the “t” in the equation: 12t − 2(t − 5) = 60 ?

First write the given equation

{:}\longrightarrow\tt 12t +2 (t-5)=60:⟶12t+2(t−5)=60

Simplify

{:}\longrightarrow\tt 12t+2t-10=60:⟶12t+2t−10=60

{:}\longrightarrow\tt 14t-10=60:⟶14t−10=60

{:}\longrightarrow\tt 14t=60+10:⟶14t=60+10

{:}\longrightarrow\tt 14t=70:⟶14t=70

{:}\longrightarrow\tt t=\cancel{\dfrac {70}{14}}:⟶t=

14

70

{:}\longrightarrow\tt t=5:⟶t=5

\therefore\sf t=5∴t=5
