You can put this solution on YOUR website!
a) 2x-2(2-x)=40 \r
\n" ); document.write( "\n" ); document.write( "2x-4+2x=40
\n" ); document.write( "4x-4=40
\n" ); document.write( "4x=44
\n" ); document.write( "x=11\r
\n" ); document.write( "\n" ); document.write( "b) 2(2x+4)=-3(2x+1)\r
\n" ); document.write( "\n" ); document.write( "4x+8=-6x-3
\n" ); document.write( "10x=-11
\n" ); document.write( "x=-1.1
\n" ); document.write( "
\n" ); document.write( "c) 12-(3x-2)=2(x-1)+3x\r
\n" ); document.write( "\n" ); document.write( "12-3x+2=2x-2+3x
\n" ); document.write( "-8x=-16
\n" ); document.write( "x=2
\n" ); document.write( "
\n" ); document.write( "d) -3(x-2)=5(2x-12)\r
\n" ); document.write( "\n" ); document.write( "-3x+6=10x-60\r
\n" ); document.write( "\n" ); document.write( "-13x=-66
\n" ); document.write( "x=66/13\r
