If 2x-y=4 then 6x-3y=?

(a)15
(b)12
(c)18
(d)10

• 3(2x-y)=3*4=12

• 6x-3y=3*(2x-y)
  =3*4
  =12
• 13 years agoHelpfull: Yes(6) No(1)
• 2x-y=4
  multiply 3 with the above equation we get 6x-3y=12..so the answer is 12.

  2x-y=4
  3*(2x-y)=3*4
  6x-3y=12

• x=3 and y=2
  so, 6x-3y=18-6=12
  so answer=12
