Question 315175
1.{{{2x-4y=-4}}}
2.{{{4x+5y=48}}}
Multiply eq. 1 by (-2) and add to eq. 2,
{{{-4x+8y+4x+5y=8+48}}}
{{{13y=56}}}
{{{highlight( y=56/13)}}}
Then use either equation to solve for x.
{{{2x-4y=-4}}}
{{{2x-4(56/13)=-52/13}}}
{{{2x=-52/13+224/13}}}
{{{2x=172/13}}}
{{{highlight( x=86/13)}}}
