3200\geq k+3175
Multiply both sides of the equation by -25. Since -25 is negative, the inequality direction is changed.
k+3175\leq 3200
Swap sides so that all variable terms are on the left hand side. This changes the sign direction.
k\leq 3200-3175
Subtract 3175 from both sides.
k\leq 25
Subtract 3175 from 3200 to get 25.
