a=x+y+z/3

y = a - 3x - z
y = a - x - 3z
y = 3a - x - z

Answer 1

\(\Large \color{purple}{3a = x + y + z }\)
\(\Large \color{purple}{ y = 3a - x - z }\)
(By transposing)

Answer 2

\[a =x+y+ \frac{z}{3}\]
Multiply each term by 3

Tell me what do you get?

Answer 3

@Diyadiya It's the whole term divided by 3 :)
