Solve for u
u\leq 16

Copied to clipboard
2u+9\leq 41
Swap sides so that all variable terms are on the left hand side. This changes the sign direction.
2u\leq 41-9
Subtract 9 from both sides.
2u\leq 32
Subtract 9 from 41 to get 32.
u\leq \frac{32}{2}
Divide both sides by 2. Since 2 is positive, the inequality direction remains the same.
u\leq 16
Divide 32 by 2 to get 16.
