Answer:

See below.

Explanation:

We are asked to solve for y.

We immediately should know that there is 2 variables, meaning that it's impossible to prove y equals a whole number value.

To solve for y, let's subtract 3x from both sides.

Subtract:


-7y=19-3x

Divide by -7:


y=(19-3x)/(-7) \ (Simplified)

Our final answer is
y=(19-3x)/(-7) .

3x-7y=19 \\ 3x-19=7y \\ y=(3x-19)/(7)
