Answer:
Step-by-step explanation:
An equivalent equality, is one that would result in the same basic value.
For example,
[tex]2x < 10[/tex] is equivalent to [tex]x < 5[/tex], however, do not mess with negative values since that can overturn your inequality sign.
An example I can think of, off the top of my head, that would use your values but still result in an equivalent expression could be something like:
[tex]y + k \leq -4 + k[/tex]
This is because, you can simply subtract [tex]k[/tex] from both sides and result in the original inequality [tex]y\leq -4[/tex].
P.S. you can also substitute any number for [tex]k[/tex] as well! Just make sure that both sides have that exact same value.
For example:
[tex]y + 3 \leq -4 + 3[/tex]
