1/2x1/4y=7/2
3/4x+1/3y=19/2
How do i change these into y=?

First thing I would do is get rid of my fractions by multiplying each term by the LCD
so multiply by 4
1/2x1/4y=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.
