Solve by the substitution method
\n" ); document.write( "6x + 2y =-46
\n" ); document.write( "-7x+ y = 57
\n" ); document.write( ":
\n" ); document.write( "Use the 2nd equation for substitution in the 1st equation
\n" ); document.write( "-7x + y = 57
\n" ); document.write( "y = 7x + 57
\n" ); document.write( ":
\n" ); document.write( "Replace y with (7x+57) in the 1st equation
\n" ); document.write( "6x + 2(7x+57) = -46
\n" ); document.write( "6x + 14x + 114 = -46
\n" ); document.write( "6x + 14x = -46 - 114
\n" ); document.write( "20x = -160
\n" ); document.write( "x = \"%28-160%29%2F20\"
\n" ); document.write( "x = -8
\n" ); document.write( ":
\n" ); document.write( "Find y, substitute -8 for x in: y = 7x + 57
\n" ); document.write( "y = 7(-8) + 57
\n" ); document.write( "y = -56 + 57
\n" ); document.write( "y = 1
\n" ); document.write( ":
\n" ); document.write( "Check solutions in the 1st equation: 6x + 2y =-46
\n" ); document.write( "6(-8) + 2(1) =
\n" ); document.write( "-48 + 2 = -46, confirms our solutions of x=-8, y=1
\n" ); document.write( "
\n" );
