.
\n" ); document.write( "4x + 3y = 5 . Multiply this by 3.
\n" ); document.write( "6x - 4y = -18 . Multiply this by 2.
\n" ); document.write( ".
\n" ); document.write( "12x+9y=15
\n" ); document.write( "12x-8y=-36 . Subtract this from above.
\n" ); document.write( ".
\n" ); document.write( "17y=51
\n" ); document.write( "y=3
\n" ); document.write( ".
\n" ); document.write( "4x+3y=5 Put in value for y.
\n" ); document.write( "4x+3(3)=5
\n" ); document.write( "4x+9=5
\n" ); document.write( "4x=-4
\n" ); document.write( "x=-1
\n" ); document.write( ".
\n" ); document.write( "ANSWER 1: First Question: x=-1, y=3
\n" ); document.write( ".
\n" ); document.write( "First equation:
\n" ); document.write( "-12x-2y=7
\n" ); document.write( "-2y=12x+7
\n" ); document.write( "y=-6-(7/2)
\n" ); document.write( "Slope=-6
\n" ); document.write( ".
\n" ); document.write( "Second equation:
\n" ); document.write( "18x + 3y = -18 , Divide by 3
\n" ); document.write( "6x+y=-6 . Multiply by 2.
\n" ); document.write( "12x+2y=-12
\n" ); document.write( "2y=-12x-12
\n" ); document.write( "y=-6x-2
\n" ); document.write( "Slope=-6
\n" ); document.write( "Slopes of these two lines are equal. No intersection.
\n" ); document.write( "ANSWER 2: Question 2 - Inconsistent system.
