See below

Explanation:

we want to subtract 61 from both sides to get an inequality with the variable isoloted

#13x<=-61#

now simply divide by a form of one in this case #13/13#

#(13x)/13 <= -61/13#

#x <= -61/13#

so #x# can only be #-61/13# or less

interval notation #(-oo, -61/13]#

we use a bracket because its a soft inequality meaning it equals a value too.

set builder would be #{x| x<= - 61/13}#
