Select the correct answer.

Which inequality is equivalent to the given inequality?

[tex]\[ -4(x+7) \ \textless \ 3(x-2) \][/tex]

A. [tex]\(-7x \ \textless \ -34\)[/tex]
B. [tex]\(-7x \ \textless \ 22\)[/tex]
C. [tex]\(-7x \ \textgreater \ 22\)[/tex]
D. [tex]\(-7x \ \textgreater \ -34\)[/tex]



Answer :

To find an inequality equivalent to the given one, we start with the original inequality and simplify.

Original inequality:
[tex]\[ -4(x + 7) < 3(x - 2) \][/tex]

Step 1: Distribute the constants within the parentheses.

Left side:
[tex]\[ -4(x + 7) = -4x - 28 \][/tex]
Right side:
[tex]\[ 3(x - 2) = 3x - 6 \][/tex]

So the inequality becomes:
[tex]\[ -4x - 28 < 3x - 6 \][/tex]

Step 2: Combine like terms. First, let's move all terms involving [tex]\(x\)[/tex] to one side and constants to the other.

Add [tex]\(4x\)[/tex] to both sides:
[tex]\[ -28 < 7x - 6 \][/tex]

Step 3: Isolate the variable [tex]\(x\)[/tex]. Add 6 to both sides:
[tex]\[ -28 + 6 < 7x \][/tex]
[tex]\[ -22 < 7x \][/tex]

Step 4: Rewrite the inequality to isolate [tex]\(x\)[/tex]. Divide both sides by 7 (keeping in mind that dividing both sides of an inequality by a positive number does not change the direction of the inequality):
[tex]\[ -\frac{22}{7} < x \][/tex]

This can also be written as:
[tex]\[ x > -\frac{22}{7} \][/tex]

Step 5: Rewrite the inequality in standard form for comparison if needed. Inverting it results in:
[tex]\[ 7x > -22 \][/tex]

But we should normalize it back as the original format:
[tex]\[ -7x < 22 \][/tex]

So, the equivalent inequality to [tex]\( -4(x + 7) < 3(x - 2) \)[/tex] is:
[tex]\[ -7x < 22 \][/tex]

Therefore, the correct answer is:
[tex]\[ \boxed{-7x < 22} \][/tex]
