math

what is the inverse of of the function x + 2y = 0 ?

__________________

y = -2x..... i hope it isn't too late, hehe

is that like making y the subject ? then shouldn't it be :

x=-2y
2y=-x

y=-1/2 x

Math = brrr :sad:

Math is allright for me... esp. Algebra
But things can get pretty ick when it comes to worded problems.

it could be too late

but here it is.. the work

x+2y=0 (take a "x" from both sides)

2y=-x (divide both sides by 2)

y=-(1/2)x

then switch x's and y's

x=-(1/2)y

solve for y by multiplying both sides by -2

y=-2x is the answer



:rolleyes
