dybincka [34]

If your solving for x, you need to isolate/get the variable "x" by itself in the inequality:

-24 ≤ 3x - 9        First add 9 on both sides

-24 + 9 ≤ 3x - 9 + 9

-15 ≤ 3x        Then divide 3 on both sides to get "x" by itself

\frac{-15}{3} \leq \frac{3x}{3}

-5 ≤ x                  [or  x ≥ -5 if you prefer "x" to be on the left side]

Solve for x 3x + 3 − x + (−7) &gt; 6 A. x &gt; (−5) B. x &gt; 2.5 C. x &gt; 5 D. x &lt; 5
denpristay [2]

ANSWER

C. x>5

EXPLANATION

The given inequality is:

3x + 3 − x + (−7) > 6

Deal with the parenthesis first to obtain;

3x + 3 − x −7 > 6

Group similar terms to get:

3x − x> 6-3+7

Combine similar terms to get,

2x \:  > \:  10

Divide both sides by 2 to obtain:

x \:  >  \: 5

The correct choice is C. x>5
