document.write( "Question 290443: If 8 is added to twice a number and this sum is multiplied by five, the result is the same as if the number is multiplied by 5 and 10 is added to the product. What is the number? Anything you can do will help. Thank you. \n" ); document.write( "
Algebra.Com's Answer #210167 by toidayma(44) You can put this solution on YOUR website! Well, this problem is rather easy if you understand the question. \n" ); document.write( "Let the number be x. \n" ); document.write( "If 8 is add to twice the number and this sum is multiplied by five -> this equals to (8 + 2*x)*5 \n" ); document.write( "If the number is multiplied by five and 10 is added to the product -> this equals to 5*x + 10. \n" ); document.write( "As told in the question, the first result is equal to the second result, which means: \n" ); document.write( "(8+2*x)*5 = 5*x + 10 \n" ); document.write( "<-> 40 + 10*x = 5x + 10 \n" ); document.write( "<-> 5*x = -30 \n" ); document.write( "<-> x = -6. \n" ); document.write( "So the number is -6. Clear, right? \n" ); document.write( " |
