Algebra.Com's Answer #92053 by checkley71(8403)![]() ![]() ![]() You can put this solution on YOUR website! sqrt(7x+2)-2=7x \n" ); document.write( "sqrt(7x+2)=7x+2 can't be that a square root of a term equals the same term UNLESS the term is=1. \n" ); document.write( "thus 7x+2=1 \n" ); document.write( "7x=1-2 \n" ); document.write( "7x=-1 \n" ); document.write( "x=-1/7 answer proof \n" ); document.write( "sqrt(7*-1/7-2)-2=7*-1/7 \n" ); document.write( "sqrt(-1+2)-2)=-1 \n" ); document.write( "sqrt(1)-2=-1 \n" ); document.write( "sqrt(1)=2-1 \n" ); document.write( "1=1\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
