Choose the equivalent system of linear equations that will produce the same solution as the one given below.4x − y = −112x + 3y = 5 −4x − 9y = −21−10y = −30 4x + 3y = 52y = −6 7x − 3y = −119x = −6 12x − 3y = −3314x = −28

a)3(4x-y=-11)=>12x-3y=-33
   2x-3y=5
  12x-3y=-33
14x=-28
x=-2 then substitute back to equation and 4-3y=5 and y=3
a)(-2,3)
b)y=3 and substitute 3 in equation for y so -4x-27=-21 and x=-3/2
(-3/2,3)
c) y=-3 and substitute it back to equation so there for the 4x-3(3)=5 andx=7/2
(7/2,-3)
d)(-2/3,19/9)
e)(-2,3)
so a and e are the same equations.
