To solve this problem by substitution method:
\n" ); document.write( "2x - 3y = -25
\n" ); document.write( "3x + y = 1\r
\n" ); document.write( "\n" ); document.write( "If you notice in the second equation, there is a y by itself (no number attached):
\n" ); document.write( "\"3x+%2B+y+=+1\"\r
\n" ); document.write( "\n" ); document.write( "First, subtract the 3x from the left to the right side of the equation:\r
\n" ); document.write( "\n" ); document.write( "\"y+=+-3x+%2B+1\"\r
\n" ); document.write( "\n" ); document.write( "Now place the y equals into the first equation:\r
\n" ); document.write( "\n" ); document.write( "\"2x+-+3y+=+-25\"
\n" ); document.write( "\"2x+-+3%28-3x+%2B+1%29+=+-25\"\r
\n" ); document.write( "\n" ); document.write( "Now follow order of operations:
\n" ); document.write( "Remember: Negative X Negative = Positive
\n" ); document.write( "\"2x+%2B+9x+-+3+=+-25\"\r
\n" ); document.write( "\n" ); document.write( "Now add like terms, x's:\r
\n" ); document.write( "\n" ); document.write( "\"11x+-+3+=+-25\"\r
\n" ); document.write( "\n" ); document.write( "To get 11x by itself, add the 3 from the left to the right side of the equation:\r
\n" ); document.write( "\n" ); document.write( "\"11x+=+-25+%2B+3\"\r
\n" ); document.write( "\n" ); document.write( "\"11x+=+-22\"\r
\n" ); document.write( "\n" ); document.write( "\"11x%2F11+=+-22%2F11\"
\n" ); document.write( "\"x+=+-2\"\r
\n" ); document.write( "\n" ); document.write( "Now you have the value of x, next place the x value into the first equation:\r
\n" ); document.write( "\n" ); document.write( "\"2%28-2%29+-+3y+=+-25\"\r
\n" ); document.write( "\n" ); document.write( "\"-4+-+3y+=+-25\"\r
\n" ); document.write( "\n" ); document.write( "Next add the 4 from the left to the right side of the equation:\r
\n" ); document.write( "\n" ); document.write( "\"-3y+=+-25+%2B+4\"\r
\n" ); document.write( "\n" ); document.write( "\"-3y+=+-21\"\r
\n" ); document.write( "\n" ); document.write( "Divide by negative 3 to get y by itself, Negative/Negative = Positive:
\n" ); document.write( "\"-3y%2F-3+=+-21%2F-3\"\r
\n" ); document.write( "\n" ); document.write( "\"y+=+7\"\r
\n" ); document.write( "\n" ); document.write( "Check both your values, x = -2, y = 7\r
\n" ); document.write( "\n" ); document.write( "Place it into either equation I placed it into the first,
\n" ); document.write( "\"2x+-+3y+=+-25\"
\n" ); document.write( "\"2%28-2%29+-+3%287%29=+-25\"
\n" ); document.write( "\"-4+-+21+=+-25\"
\n" ); document.write( "\"-25+=+-25\"\r
\n" ); document.write( "\n" ); document.write( "
