-3-(-4x)= -4x+5
\n" ); document.write( "-3+3+4x= -4x+5+3
\n" ); document.write( "4x+4x= -4x+4x+8
\n" ); document.write( "8x=8
\n" ); document.write( "8x/8=8/8
\n" ); document.write( "x=1
\n" ); document.write( ".
\n" ); document.write( "Check by pluggin x=1 back into the equation:
\n" ); document.write( "-3-(-4x)= -4x+5
\n" ); document.write( "-3-(-4)(1)= (-4)(1)+5
\n" ); document.write( "-3+4=-4+5
\n" ); document.write( "1=1 (Checks out)
