5u-10\leq 45
Swap sides so that all variable terms are on the left hand side. This changes the sign direction.
5u\leq 45+10
Add 10 to both sides.
5u\leq 55
Add 45 and 10 to get 55.
u\leq \frac{55}{5}
Divide both sides by 5. Since 5 is positive, the inequality direction remains the same.
u\leq 11
Divide 55 by 5 to get 11.
