Solve by using Elimination.
\n" ); document.write( "1/14x + 1/2y = 11/7
\n" ); document.write( "1/3x + 2/15y = -38/15
\n" ); document.write( "--------------------------
\n" ); document.write( "multiply thru the 1st equation by 14
\n" ); document.write( "multiply thru the 2nd equation by 15
\n" ); document.write( "-----------------------------------------
\n" ); document.write( "x + 7y = 22
\n" ); document.write( "5x + 2y = -38
\n" ); document.write( "--------------------
\n" ); document.write( "Multiply thru the 1st equation by 5:
\n" ); document.write( "5x + 35y = 110
\n" ); document.write( "5x + 2y = -38
\n" ); document.write( "---------------------
\n" ); document.write( "Subtract the 2nd from the 1st and solve for \"y\":
\n" ); document.write( "33y = 148
\n" ); document.write( "y = 148/33
\n" ); document.write( "---
\n" ); document.write( "Substitute into x + 7y = 22 to solve for \"x\":
\n" ); document.write( "x + 7(148/33) = 22
\n" ); document.write( "x = -310/33
\n" ); document.write( "--------------------------
