6x+2y-4=0
\n" ); document.write( "10x+7y=-8
\n" ); document.write( "-----------
\n" ); document.write( "Rearrange
\n" ); document.write( "6x + 2y = 4
\n" ); document.write( "10x+ 7y = -8
\n" ); document.write( "--------------------
\n" ); document.write( "Multiply thru the 1st Eq. by 7
\n" ); document.write( "Multiply thru the 2nd Eq. by 2
\n" ); document.write( "--------------------
\n" ); document.write( "42x + 14y = 28
\n" ); document.write( "20x + 14y = -16
\n" ); document.write( "------------------------
\n" ); document.write( "Subtract the 2nd equation from the 1st:
\n" ); document.write( "22x = 44
\n" ); document.write( "x = 2
\n" ); document.write( "--------------------
\n" ); document.write( "Subtract x=2 into 6x+2y = 4 to solve for \"y\":
\n" ); document.write( "6*2 + 2y = 4
\n" ); document.write( "2y = -8
\n" ); document.write( "y = -4
\n" ); document.write( "==========================
