The value of y for the equation $3x+2y-4=0$ is $-\frac{3x}{2}+2$.
Consider the equation; $3x+2y-4=0$ Solve the equation for y, \begin{align} & 3x+2y-4=0 \\ & 2y=4-3x \\ & y=\frac{4-3x}{2} \end{align} Therefore, \begin{align} & y=-\frac{3x}{2}+\frac{4}{2} \\ & y=-\frac{3x}{2}+2 \end{align} Hence, the solution of y for the equation $3x+2y-4=0$ is $-\frac{3x}{2}+2$.
