solve the following by method of substitution:
\n" ); document.write( "{3x-2y=13
\n" ); document.write( "{x+y=1
\n" ); document.write( "----
\n" ); document.write( "Solve the 2nd equation for \"x\":
\n" ); document.write( "x = 1-y
\n" ); document.write( "----
\n" ); document.write( "Substitute that value of \"x\" into the 1st equation
\n" ); document.write( "and solve for \"y\":
\n" ); document.write( "---
\n" ); document.write( "3(1-y) -2y = 13
\n" ); document.write( "3-3y-2y = 13
\n" ); document.write( "-5y = 10
\n" ); document.write( "y = -2
\n" ); document.write( "------------
\n" ); document.write( "Since x = 1-y, x = 1--2 = 3
\n" ); document.write( "------------------------------
\n" ); document.write( "Solution (3,-2)
