let class photo be $x
\n" ); document.write( "wallet photo be $y
\n" ); document.write( "..
\n" ); document.write( "x+12y=25.................1
\n" ); document.write( "2x+20y=44................2
\n" ); document.write( "..
\n" ); document.write( "multiply equation 1 by -2
\n" ); document.write( "-2x-24y=-50
\n" ); document.write( "2x+20y = 44
\n" ); document.write( "Add the equations
\n" ); document.write( "-4y=-6
\n" ); document.write( "divide by -4
\n" ); document.write( "y= -6/-4
\n" ); document.write( "y=$1.5 cost of wallet photo
\n" ); document.write( "plug the value of y in equation 1
\n" ); document.write( "x+18=25
\n" ); document.write( "x=7 the cost of class photo.
\n" ); document.write( "
\n" );
