ANSWER and EXPLANATION
We are given two inequalities:
[tex]y\text{ + 4 }\leq6\text{ and y - 4 }\leq6[/tex]
Let us solve both of them:
[tex]\begin{gathered} y\text{ + 4 }\leq6 \\ \Rightarrow\text{ y }\leq\text{ 6 - 4} \\ y\text{ }\leq2 \\ \\ y\text{ - 4 }\leq\text{ 6} \\ \Rightarrow\text{ y }\leq\text{ 6 + 4} \\ y\text{ }\leq\text{ 10} \end{gathered}[/tex]
Now let us compare and contrast
SIMLIARITY
For the both of them, we collect the like terms by taking the numerical terms to the right hand side.
DIFFERENCES
For the first one, we subtract 4 from 6 because its sign changes after taking it to the right hand side while for the second one, we add 4, for the same reason.
