You can put this solution on YOUR website!
example:
3x-10=14--------equation
3x--------------first multiply by 3
3x-10----------now,10 is subtracted from 3x
3x-10=14-------the result
(2)-3*x/10<3
(3)[-5,3)

Only 1 problem per post, as per site instructions. Did you read them?

I'll do the first.

3x - 4y = 5 for y

- 4y = - 3x + 5 ----- Subtracting 3x to begin the process of isolating y

y+=+%28%28-+3%29%2F-+4%29x+%2B+5%2F-+4 ----- Dividing by - 4 to isolate y

highlight_green%28y+=+%283%2F4%29x+-+5%2F4%29
