solve each by the substitution method.
\n" ); document.write( "Y=2x+6
\n" ); document.write( "3x-2y=-11
\n" ); document.write( "---
\n" ); document.write( "Substitute for \"y\" and solve for \"x\":
\n" ); document.write( "3x - 2(2x+6) = -11
\n" ); document.write( "3x - 4x - 12 = -11
\n" ); document.write( "-x = 1
\n" ); document.write( "x = -1
\n" ); document.write( "---
\n" ); document.write( "Solve for \"y\":
\n" ); document.write( "y = 2x+6
\n" ); document.write( "y = 2*-1+6
\n" ); document.write( "y = 4
\n" ); document.write( "-----------------\r
\n" ); document.write( "\n" ); document.write( "x+3y=-3
\n" ); document.write( "2x+y=4
\n" ); document.write( "----
\n" ); document.write( "Solve 1st for \"y\":
\n" ); document.write( "y = 4-2x
\n" ); document.write( "---
\n" ); document.write( "Substitute for \"y\" and solve for \"x\":
\n" ); document.write( "x + 3(4-2x) = -3
\n" ); document.write( "x + 12 - 6x = -3
\n" ); document.write( "-5x = -15
\n" ); document.write( "x = 3
\n" ); document.write( "---
\n" ); document.write( "Solve for \"y\":
\n" ); document.write( "y = 4-2x
\n" ); document.write( "y = 4-2*3
\n" ); document.write( "y = -2
