find the value of y if the mean of 22, 18, (2y+1) 10 and 20 is 25
\n" ); document.write( " $\"%28%2822%2B18%2B%282y%2B1%29%2B10%2B20%29%29%2F6\"$ = 25
\n" ); document.write( "Multiply both sides by 6
\n" ); document.write( "22+18+(2y+1)+10+20 = 6*25
\n" ); document.write( "2y + 71 = 150
\n" ); document.write( "2y = 150 - 71
\n" ); document.write( "2y = 79
\n" ); document.write( "y = 79/2
\n" ); document.write( "y = 39.5
\n" ); document.write( ":
