document.write( "Question 77777: My equation is 5x+8+3x-x+5=6x-3 I have gotten the answer which is -16 and checked it on the equation solver. What I do not understand is why I am not coming out with the correct answer when I check the problem by replacing x with -16? Can someone help me with checking the work?
\n" );
document.write( "I have 5(-16)+8+3(-16)-16+5=6(-16)-3 but it is not coming out equal on both sides. \n" );

Algebra.Com's Answer #55772 by bucky(2189)![]() ![]() ![]() You can put this solution on YOUR website! Your answer of x = -16 is correct. \n" ); document.write( ". \n" ); document.write( "Your \"check\" is: \n" ); document.write( ". \n" ); document.write( "5(-16) + 8 + 3(-16) -16 + 5 = 6(-16) - 3 \n" ); document.write( ". \n" ); document.write( "The first three terms [5(-16) + 8 + 3(-16)] are correct. The next term should be -(-16) = +16 \n" ); document.write( "not -16. All the rest is OK. \n" ); document.write( ". \n" ); document.write( "Your check should further simplify to: \n" ); document.write( ". \n" ); document.write( "-80 + 8 - 48 + 16 + 5 = -96 - 3 \n" ); document.write( ". \n" ); document.write( "and if you add the terms on each side you get - 99 = - 99 \n" ); document.write( ". \n" ); document.write( "Hope this eases your mind. Just a minor error. \n" ); document.write( " \n" ); document.write( " |
