4(x-1)-(9x-5)≥7

4х-4-9х+5≥7

-5х≥7-1

-5х≥6 |:(-5)

х≥-6/5

х<=-1 1/5

ответ:[-бесконечности;-1 1/5]

Answer 3

To solve the inequality, follow these steps:

Step 1: Simplify the expression on the left-hand side (LHS) of the inequality: 4(x - 1) - (9x - 5) ≥ 7

First, distribute the 4 on the left side: 4x - 4 - (9x - 5) ≥ 7

Now, distribute the negative sign inside the parentheses on the right side: 4x - 4 - 9x + 5 ≥ 7

Combine like terms: (4x - 9x) + (5 - 4) ≥ 7 -5x + 1 ≥ 7

Step 2: Isolate the variable (x) on one side of the inequality. To do this, we'll move the constant term to the other side by subtracting 1 from both sides:

-5x + 1 - 1 ≥ 7 - 1 -5x ≥ 6

Step 3: Divide both sides of the inequality by -5. Remember to reverse the inequality when dividing by a negative number:

(-5x)/(-5) ≤ 6/(-5)

x ≤ -6/5

So, the solution to the inequality is x ≤ -6/5.
