First of all, convert 3|y+51|-15=6 to
\n" ); document.write( " 3|y+51| = 21 by adding 15 on both sides
\n" ); document.write( " then dividing by 7:
\n" ); document.write( " |y + 51| = 7
\n" ); document.write( " By definition of absolute value,we see that |x| = b is equivalent
\n" ); document.write( " to the equations x = b or x = -b.\r
\n" ); document.write( "\n" ); document.write( " Hence,|y + 51| = 7 is equivalent
\n" ); document.write( " to y + 51 = 7...(1)
\n" ); document.write( " or y + 51 = -7...(2)
\n" ); document.write( " From (1): y = -44
\n" ); document.write( " From (1): y = -58\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
