Solvex +6> 10,x + 16>20,x + 26 > 30. Complete the description of a pattem. Then use the pattern to
predict the solution of x + 4 446 > 4,450.

For each Inequality, x> ( ) and the number added to x Is ( ) less than the number on the
right side of each inequality. So,X> ( ) is the solution of x + 4,446 > 4,450.
