Question 147692
solve using elimination method and check

   4x+y=1
    x-2y=-2

Multiply the second equation by -4 to be able to eliminate x.  You should get {{{-4x+8y=8}}}.  Add all that to the first equation and get {{{9y=9}}}. So y=1.  Plug 1 in for y in the other equation to solve for x.  {{{4x+1=1}}}. {{{4x=0}}}. x=0. To check both values, plug them both into either equation. {{{0-2=-2}}}. It's true. So x=0 and y=1.
