9 - 0.75(x+8) - 5 = -2
\n" ); document.write( "9-.75x-6-5=-2
\n" ); document.write( "-.75x=-2-9+6+5
\n" ); document.write( "-.75x=0
\n" ); document.write( "x=0/-.75
\n" ); document.write( "x=0 ans.
\n" ); document.write( "Proof:
\n" ); document.write( "9-.75(0+8)-5=-2
\n" ); document.write( "9-6-5=-2
\n" ); document.write( "-2=-2
\n" ); document.write( "-----------------------------------------\r
\n" ); document.write( "\n" ); document.write( "15 - 8(x-6)
\n" ); document.write( "-------------- = -2.25
\n" ); document.write( " 4
\n" ); document.write( "15-8(x-6)=-2.25*4
\n" ); document.write( "15-8x+48=9
\n" ); document.write( "-8x=9-15-48
\n" ); document.write( "-8x=-54
\n" ); document.write( "x=-54/-8
\n" ); document.write( "x=6.75 ans.
\n" ); document.write( "Proof:
\n" ); document.write( "(15-8(6.75-6))/4=-2.25
\n" ); document.write( "(15-8*.75)=4*-2.25
\n" ); document.write( "15-6=9
