Question

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

Answer 1

• First write the given equation

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

• Simplify

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

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

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

`{:}\longrightarrow\tt 14t=70`

`{:}\longrightarrow\tt t=\cancel{\frac {70}{14}}`

`{:}\longrightarrow\tt t=5`

`\therefore\sf t=5`
