4 a + 3 b = -5 .............1
\n" ); document.write( "1 a -1 b = -3 .............2
\n" ); document.write( "
\n" ); document.write( "multiply (1)by 1
\n" ); document.write( "Multiply (2) by 3
\n" ); document.write( "4 a + 3 b = -5
\n" ); document.write( "3 a -3 b = -9
\n" ); document.write( "Add the two equations
\n" ); document.write( "7 a = -14
\n" ); document.write( "/ 7
\n" ); document.write( "a =-2
\n" ); document.write( "plug value of a in (1)
\n" ); document.write( "4 a + 3 b = -5
\n" ); document.write( "-8 + 3 b = -5
\n" ); document.write( " 3 b = -5 + 8
\n" ); document.write( " 3 b = 3
\n" ); document.write( " b = 1
\n" ); document.write( " \n" ); document.write( "
