Solve the inequality:
[tex]\[ -4x + 7 \ \textgreater \ 19 \][/tex]

Is it equivalent to which of the following?

A. [tex]\[ x \ \textless \ -3 \][/tex]

B. [tex]\[ x \ \textgreater \ -3 \][/tex]

C. [tex]\[ x \ \textless \ -6 \][/tex]

D. [tex]\[ x \ \textgreater \ -6 \][/tex]



Answer :

Let's solve the inequality step-by-step.

We start with the given inequality:
[tex]\[ -4x + 7 > 19 \][/tex]

Step 1: Subtract 7 from both sides of the inequality to isolate the term with [tex]\( x \)[/tex].

[tex]\[ -4x + 7 - 7 > 19 - 7 \][/tex]

This simplifies to:

[tex]\[ -4x > 12 \][/tex]

Step 2: Divide both sides of the inequality by [tex]\(-4\)[/tex]. Remember that when you divide or multiply both sides of an inequality by a negative number, you must reverse the direction of the inequality.

[tex]\[ x < \frac{12}{-4} \][/tex]

[tex]\[ x < -3 \][/tex]

So, the original inequality [tex]\( -4x + 7 > 19 \)[/tex] is equivalent to:
[tex]\[ x < -3 \][/tex]
