Solve x – 2y = 4 for y.

Answer 1

Are they wanting to use x from the previous problem?

Answer 2

no i ment to put that they are two difffrent Q

Answer 3

if so that would be
8 - 2y = 4
2y - 8 = 4
-8 -8
2y = -4
y = -2

if not it would be

1 - 2y = 4
2y - 1 = 4
2y = 3
y = .6 with a repeating bar above the 6

Answer 4

x automatically is substituted for 1 because it's simply x, so that's how I got the 1, if you were wondering.
