Ответ:

-63-9x-3x≥-9

-12x≥54

x≤(-54/12)

x≤ (-9/2)

xє(-inf: -4.5]

Answer 3

To solve the inequality, let's simplify the expression and isolate the variable x step by step:

-9(7 + x) - 3x ≥ -9

Start by distributing -9 to the terms inside the parentheses:

-63 - 9x - 3x ≥ -9

Combine like terms:

-63 - 12x ≥ -9

Next, let's isolate the variable x by bringing constant terms to the other side of the inequality:

-12x ≥ -9 + 63

-12x ≥ 54

Now, divide both sides of the inequality by -12. Since we are dividing by a negative number, we need to reverse the inequality sign:

x ≤ 54 / -12

Simplifying the right side:

x ≤ -4.5

Therefore, the solution to the inequality is x ≤ -4.5.
