### Don't understand this equation

There is an equation in my book: Solve for y in the equation " $3x+y+1=0$ ". Um... how would I solve that?

You can see the general process here.

(As you'll see when you study the lesson, solving literal equations is very much like solving linear equations.)

The only real difference between solving the linear equation "3 + y + 1 = 0" and the literal equation "3x + y + 1 = 0" is that you can't simplify as much, because of the second variable.
