Hi,
{{{3*2x - 3*y = 1*3}}}       |multiplying {{{2x-y = 1}}} thru by 3 to  eliminate the y variable
<u>   x +  3y =  4</u>    
     7x = 7 ,     x = 1  and y = 1    | ({{{2*1 - y = 1}}})
      8x + 5y = 13  
 <u>{{{5*3x-5*y= 5*2}}}</u>        |multiplying {{{3x-y = 2}}} thru by 5 to  eliminate the y variable
         23x = 23 ,     x = 1  and y = 1   | ({{{3*1 - y = 2}}})
