Question

solve the equation for y 1/3x + y = 4

Answer 1

The given expression is,

$(\frac{1}{3}x)+y=4$

On solving,

$\begin{gathered} \frac{x}{3}+y=4 \\ x=12-3y \end{gathered}$

Substituting the value of x in the first equation,

$\begin{gathered} \frac{12-3y}{3}+y=4 \\ 12-3y+3y=12 \\ y=0 \end{gathered}$

Thus, y =0
