1/2x-1/4y=7/2
3/4x+1/3y=19/2

How do i change these into y=?

  • math - ,

    First thing I would do is get rid of my fractions by multiplying each term by the LCD
    so multiply by 4
    1/2x-1/4y=7/2
    2x - y = 14
    Take all terms except the y term to the right side
    -y = -2x + 14
    divide by -1
    y = 2x - 14

    repeat the same steps for your second equation and let me know what you got.
