n = 4
Step-by-step explanation: you combine the like variables which turns it into
(4y - 3)
(4y - 3) is another way of saying ((4 x y) - 3)
So the 4 is turned into n making it (ny - 3)
Step-by-step explanation:
(y+2) + (3y-5) = (ny-3)
Step 1: Remove the brackets as the terms in brackets are separated by an addition sign.
y + 2 + 3y - 5 = ny - 3
Step 2: Join the like-terms.
4y - 3 = ny - 3
From here, you can either do logical reasoning that n = 4 because lefthand side should be equal to righthand side or you continue by making n subject of the formula which obviously gives you 4 :)
