Question

Please help me out!

combine like terms to solve. check to justify your answer.
u + 6 + 5 is less than or equal to -4

Answer 1

u + 6 + 5 ≤ -4

u + 11 ≤ -4

Subtract 11 from both sides.

u ≤ -15

We can replace the value of u with -15, and the inequality should be the same on both sides.

-15 + 6 + 5 ≤ -4

-4 ≤ -4

The inequality is true, and so our solution is correct.
