Answer :
To solve the inequality [tex]\(-96 < x + 42\)[/tex], follow these steps:
1. Identify the First Step: You want to isolate [tex]\(x\)[/tex] on one side of the inequality. To do this, you need to get rid of the [tex]\(+42\)[/tex] that's added to [tex]\(x\)[/tex]. The best way to remove [tex]\(+42\)[/tex] is to subtract 42 from both sides of the inequality.
2. Subtract 42 from Both Sides:
[tex]\[
-96 - 42 < x + 42 - 42
\][/tex]
Simplifying the right side, the [tex]\(42\)[/tex] cancels out:
[tex]\[
-96 - 42 < x
\][/tex]
3. Calculate the Left Side:
[tex]\[
-96 - 42 = -138
\][/tex]
4. Express the Final Inequality: Now, with the simplified left side, you have:
[tex]\[
-138 < x
\][/tex]
5. Rewrite the Inequality Flipping the Sides: To have [tex]\(x\)[/tex] on the left side (common practice), rewrite the inequality:
[tex]\[
x > -138
\][/tex]
So, the solution to the inequality is [tex]\(x > -138\)[/tex]. This tells us that [tex]\(x\)[/tex] must be greater than [tex]\(-138\)[/tex].
