How do you solve for y in x plus y equals 3?

Answer 1

To "Solve" for Y which means get it on one side of the equals sign and everything else on the other side, write out your equation.

Y + X = 3

You want to get Y by itself so you would want to remove (transfer) the rest of the equation to the other side. Since X is the only thing on that side and it's positive (adding X) you will remove it. Make sure you do this to both sides though.

Y + X - X = 3 - X (simplify)

Y = 3 - X

There's your answer.
