Question 311012
Multiply both equations by 10 to eliminate decimals.
1.{{{3x-2y=40}}}
2.{{{5x+3y=710/23}}}
Mulltiply eq. 1 by 3 and eq. 2 by 2 and add them to eliminate y,
{{{9x-6y+10x+6y=120+1420/23}}}
{{{19x=2760/23+1420/23}}}
{{{highlight_green( x=4180/437)}}}
Then use either equation to solve for x.
{{{3x-2y=40}}}
{{{12540/437-2y=17480/437}}}
{{{-2y=4940/437}}}
{{{highlight_green( y=-2470/437)}}}
