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}
