Question

F (x) =3(x-2) given that f(t) =6, find t

Answer 1

`\qquad{:}\longrightarrow\tt f (x)=3 (x-2)`

`\qquad{:}\longrightarrow\tt f (t)=3 (t-2)`

ATQ

`\qquad{:}\longrightarrow\tt f(t)=6`

`\qquad{:}\longrightarrow\tt 3 (t-2)=6`

• Simplify

`\qquad{:}\longrightarrow\tt 3t-2=6`

`\qquad{:}\longrightarrow\tt 3t=6+2`

`\qquad{:}\longrightarrow\tt 3t=8`

`\qquad{:}\longrightarrow\tt t=(8)/(3)`

`\therefore\sf t=(8)/(3)`
