document.write( "Question 380386: solution steps for solving (5a+7)=(6a-7) The parenthesis are not really parenthesis. They stand for absolute value signs which I don't have on the keyboard. So the equation is the absolute value of each quantity on each side of the equation. \n" ); document.write( "
Algebra.Com's Answer #269943 by richard1234(7193) You can put this solution on YOUR website! Absolute value sign |x| is typed on a keyboard using \"shift\"+\"\\"\r \n" ); document.write( "\n" ); document.write( "There are two cases for this problem:\r \n" ); document.write( "\n" ); document.write( "5a + 7 = 6a - 7 --> a = 14\r \n" ); document.write( "\n" ); document.write( "5a + 7 = -(6a - 7) --> 5a + 7 = -6a + 7 --> a = 0\r \n" ); document.write( "\n" ); document.write( "Checking, both solutions satisfy the equation. \n" ); document.write( " |
