Using the elimination method, which variable should be eliminated first?
 $-4x+6y=\text{4}$  
 $4x+y=24$  

• x is ready to be eliminated without any changes to the equations

• y is ready to be eliminated without any changes to the equations

• x, but you have to multiply one of the equations by -1 to change the signs

• y, but you have to multiply one of the equations by -1 to change the signs
