Best ResponseYou've already chosen the best response.0Can you please do the step that I gave previously. 4x  y =8 The first step to isolate y is to subtract 4x from both sides of the equation. Can you do that?

Best ResponseYou've already chosen the best response.0Not really. Subtracting 4x from both sides gives: 4x  y  4x = 8  4x ...............(1) Can you simplify the left hand side of (1)?

Best ResponseYou've already chosen the best response.0We are looking at simplifying the left hand side of 4x  y  4x = 8  4x ...............(1) If the terms on the left hand side are rearrangedas follows is the simplification clearer? (4x  4x)  y = 8  4x Hint: What is 4x  4x ?
