1/2x - 1/4y= 7/2 3/4x + 1/3y= 19/2 To change into y=, do i multiply the top one by by 1/4 and the bottom one by -1/3?

**art**

can you use like twizzlers or something like that?

**4th**

greatly increased as by multiplication.

oh alright thanks(:

**math**

the original equation? Do you mean... -1/2(-2y)=-1/2(-1-3x)?

**math**

How do i change these into y=? 3x – 2y = –1 --> -2y= -1-3x 5x + 2y = 25 --> 2y= 25-5x
