Determine the value of the unknown
\n" ); document.write( "1.1 X-3 over4-x+2 over 3=3
\n" ); document.write( "(x-3)/4 - (x+2)/3 = 3
\n" ); document.write( "------
\n" ); document.write( "3(x-3) - 4(x+2) = 36
\n" ); document.write( "3x-9-4x-8 = 36
\n" ); document.write( "-x - 17 = 36
\n" ); document.write( "-x = 53
\n" ); document.write( "x = -53
\n" ); document.write( "----------------\r
\n" ); document.write( "\n" ); document.write( "1.2 (a-1)(a+1)=0
\n" ); document.write( "a = 1 or a = -1
\n" ); document.write( "-------------------
\n" ); document.write( "1.3 2 over 3a+7=3
\n" ); document.write( "2/(3a+7) = 3
\n" ); document.write( "2 = 9a+21
\n" ); document.write( "9a = -19
\n" ); document.write( "a = -19/9
\n" ); document.write( "-------------------
\n" ); document.write( "1.4 name four conditions for congruency
\n" ); document.write( "Congruency of what??
\n" ); document.write( "=======================
