X(4*1) because I’m just doing what I’m told.
As a rule , - times - = + and - times + = -

Therefore the correct answer to the question is 2m squared n

Cuz if so, then you just move the whole x term to the right side and divide all the terms on the right side by the coefficient of y
for ex...
3) 4x+4y=16
4y=16-4x (or -4x+16)
y=4-x or -x+4
