Question

5x-10x=-40 solve for y

Answer 1

Um, should one of those variables be "y"??

Answer 2

sorry it is this 5x-10y=-40

Answer 3

Lol. -10y=-5x-40
y= 1/2 x + 4
And thats your answer. Get it?

Answer 4

thanks so much how did you get that answer

Answer 5

When solving for y, you want everything on one side.
5x- 5x -10y= -5x-40 -->>subtract 5x from both sides
-10y/-10= -5x/-10 - 40/-10 -->> divide eveything by -10
Is it clearer?

Answer 6

yes

Answer 11

Answer 12

lol

Answer 13

Oh, duuuh. Lol.
4( 2x+3/4)= x -->> multiply each side by 4
8x+3= x
3= -7x -->> combine like terms by subtracting x and 8x. So 1-8= -7
-3/7= x --->> divide each side by -7.

Here's your answer........hopefully. Im not sure about this one.
