To solve the inequality [tex]\(3x + 3 - x - 7 > 6\)[/tex] for [tex]\(x\)[/tex], let's break it down step by step.
First, simplify the left-hand side of the inequality:
[tex]\[ 3x + 3 - x - 7 \][/tex]
Combine the [tex]\(x\)[/tex] terms together:
[tex]\[ (3x - x) = 2x \][/tex]
Combine the constant terms together:
[tex]\[ 3 - 7 = -4 \][/tex]
So, the inequality simplifies to:
[tex]\[ 2x - 4 > 6 \][/tex]
Next, isolate the [tex]\(x\)[/tex] term by adding 4 to both sides of the inequality:
[tex]\[ 2x - 4 + 4 > 6 + 4 \][/tex]
This simplifies to:
[tex]\[ 2x > 10 \][/tex]
Now, divide both sides by 2 to solve for [tex]\(x\)[/tex]:
[tex]\[ \frac{2x}{2} > \frac{10}{2} \][/tex]
Which simplifies to:
[tex]\[ x > 5 \][/tex]
Thus, the solution to the inequality [tex]\(3 x + 3 - x + (-7) > 6\)[/tex] is [tex]\(x > 5\)[/tex].
Therefore, the correct answer is:
D. [tex]\(x > 5\)[/tex]
First, simplify the left-hand side of the inequality:
[tex]\[ 3x + 3 - x - 7 \][/tex]
Combine the [tex]\(x\)[/tex] terms together:
[tex]\[ (3x - x) = 2x \][/tex]
Combine the constant terms together:
[tex]\[ 3 - 7 = -4 \][/tex]
So, the inequality simplifies to:
[tex]\[ 2x - 4 > 6 \][/tex]
Next, isolate the [tex]\(x\)[/tex] term by adding 4 to both sides of the inequality:
[tex]\[ 2x - 4 + 4 > 6 + 4 \][/tex]
This simplifies to:
[tex]\[ 2x > 10 \][/tex]
Now, divide both sides by 2 to solve for [tex]\(x\)[/tex]:
[tex]\[ \frac{2x}{2} > \frac{10}{2} \][/tex]
Which simplifies to:
[tex]\[ x > 5 \][/tex]
Thus, the solution to the inequality [tex]\(3 x + 3 - x + (-7) > 6\)[/tex] is [tex]\(x > 5\)[/tex].
Therefore, the correct answer is:
D. [tex]\(x > 5\)[/tex]
