26x-10y=100
\n" ); document.write( "add -26x to each side
\n" ); document.write( "-10y=-26x+100
\n" ); document.write( "multiply each side by -1
\n" ); document.write( "10y = 26x -100
\n" ); document.write( "divide each side by 10
\n" ); document.write( "y = (26/10)x -10
\n" ); document.write( "Using the pair (-3,y), set x = -3
\n" ); document.write( "y = (26/10)(-3) -10
\n" ); document.write( "y = -78/10 -100/10
\n" ); document.write( "y = -78/10 -100/10
\n" ); document.write( "y = -178/10
\n" ); document.write( "y = -17.8
\n" ); document.write( "substituting in the original equation,
\n" ); document.write( "26x-10y=100
\n" ); document.write( "26(-3)-10(-17.8)?=100
\n" ); document.write( "-78 + 178 = 100 This checks, so
\n" ); document.write( "the value for y in the pair (-3,y) is -17.8
\n" ); document.write( " \n" ); document.write( "
\n" );
