Question

4(х-1)-(9х-5)больше или равно 7 решите ​

Answer 1

Ответ:

Объяснение:

4(x-1)-(9x-5)$\geq$7

4x-4-9x+5$\geq$7

-5x$\geq$6

x$\geq$$\frac{6}{-5}$

Answer 2

To solve the inequality 4(x-1) - (9x-5) >= 7, follow these steps:

Step 1: Distribute and simplify the expressions within the parentheses: 4(x - 1) = 4x - 4 -(9x - 5) = -9x + 5

The inequality becomes: 4x - 4 - 9x + 5 >= 7

Step 2: Combine like terms on the left side of the inequality: (4x - 9x) + (-4 + 5) >= 7 -5x + 1 >= 7

Step 3: Isolate the variable term (x) by moving the constant term (1) to the other side of the inequality: -5x >= 7 - 1 -5x >= 6

Step 4: To solve for x, divide both sides by -5, remembering to reverse the inequality sign when dividing by a negative number: x <= 6 / -5 x <= -1.2

The solution to the inequality is x <= -1.2.
