See below

Explanation:

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

13x<=-6113x61

now simply divide by a form of one in this case 13/131313

(13x)/13 <= -61/1313x136113

x <= -61/13x6113

so xx can only be -61/136113 or less

interval notation (-oo, -61/13](,6113]

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

set builder would be {x| x<= - 61/13}{xx6113}
