What is the solution to the inequality 7<=-3x-4

kipiarov [429]

Answer:

The nearest option is -3 (negative 3)

So, Option B is correct.

Step-by-step explanation:

We need to solve the inequality $7 \leq -3x-4$

Solving:

Step 1: Switching sides of inequality and reversing the inequality

$-3x-4\geq 7$

Step 2: Adding 4 on both sides

$-3x-4+4\geq 7+4\\-3x\geq 11$

Step 3: Dividing both sides by -3 and reversing the inequality

$\frac{-3x}{-3}\leq \frac{11}{-3} \\x\leq -3.6\\$

The nearest option is -3 (negative 3)

So, Option B is correct.
