I just need help with reversing a simple equation (math)?

Question

Take this:

4x + y = -8

And reverse it so it is in a Y-Form? Like y = ... I learned this before, but since it is summer vacation, I kind of forget how to reverse it. Right now, I'm like reviewing and getting prepared for school.

Answer 1

all you have to do is move the 'unwanted' stuff to one side and leave the one that you want on the other.

in this case, leave the y where it is, and move the 4x. moving the 4x over will result in it becoming -4x. this sign switches when moving across the = sign. + becomes - and x becomes / and vice versa.

therefore, y = - 4x - y = - (4x + y)

all you need is some practise to deal with math, especially if youre rusty. good luck and (try to) have fun at school!

Answer 2

enable x be the ten's digit and y be the single's digit Our unique # = 10x + y x+ y = 12 x+ 10y = 10x + y +18 which will grow to be -9x + 9y = 18 and then dividing by technique of -9 we get x - y = -2 x + y = 12 x - y = 2 2x = 10 so x = 5 then 5 + y = 12 and y= 7 Our unique # grow to be 57 5+7= 12 seventy 5 = 57 + 18

Answer 3

y = -8 -4x

Just move over the 4x and reverse the sign so that the y is alone.

There you have it.

YAY!

Answer 4

y= -4x-8
its pretty simple all you need to remember is that to bring all the terms to one side by doing its opposite symbol!

Answer 5

y=-8-4x

Just subtract the 4x from both sides.

Answer 6

y = -4x- 8

Just switch the 4x to the right side. And if it is a positive, switch to negative and if it is a negative, switch to positive. I think it should be right?

Answer 7

subtract the 4x from both sides. so you're left with

y = -8 - 4x

hope it helps!

Answer 8

y = -8 - 4x

Answer 9

4x + y = -8
-4x + 4x + y = -4x -8
y = -4x - 8

Answer 10

4x + y = -8
-4x -4x

y= -4x-8
