anonymous · Answer

multiply the second equation by -34/12 to eliminate y and solve system through linear combinations,
 it seems none of the options are right

anonymous · Answer

the 34 is a fraction and so is the 12 so its like 1/2 and 3/4

anonymous · Answer

34/12 = 17/6 .... 
i can't see how multiplying by 1/2 or 3/4 will help to eliminate y
