First, solve the equation for y(DONE). Second, find the value of y for the given x-value(?).

3x - 2y = -7, when x = 3

I figured out the first step.
I need help with the second step? Please?

Solve for y:

$$3x-2y=-7$$group like terms and isolate positive y$$2y=3x+7$$divide by 2$$y=\frac{ 3x+7 }{ 2 }$$

Value of y when x=3:
$$y=\frac{ 3x+7 }{ 2 }$$$$y=\frac{ 3(3)+7 }{ 2 }$$$$y=\frac{ 9+7 }{ 2 }$$$$y=\frac{ 16}{ 2 }=8$$
