Question

What is 3x+12-6x≤-9 ?

Answer 1

Combine like terms and subtract 12 on the left side to the right side to get -3x=-21. divide -3 to both sides to get x=7 as your final answer.

Answer 2

Answer:

$\boxed {x \geq 7}$

Step-by-step explanation:

Solve the given inequality:

$3x + 12 - 6x \leq -9$

-Combine both $3x$ and $-6x$:

$3x + 12 - 6x \leq -9$

$-3x + 12 \leq -9$

-Subtract both sides by $12$:

$-3x + 12 - 12 \leq -9 - 12$

$-3x \leq -21$

-When you are dividing an integer by a negative integer, the inequality sign would change. So, divide both sides by $-3$:

$\frac{-3x}{-3} \leq \frac{-21}{-3}$

$\boxed {x \geq 7}$ (Final Answer)
