Question6(x3)>246-(x-3)>24

Studdy Solution

STEP 1

What is this asking? We need to find all the values of xx that make the inequality 6(x3)>246 - (x - 3) > 24 true. Watch out! Don't forget to flip the inequality sign when multiplying or dividing by a negative number!

STEP 2

1. Simplify the left side.
2. Isolate the xx term.
3. Solve for xx.

STEP 3

First, we **distribute** the negative sign across the parentheses.
Remember, subtracting (x3)(x-3) is the same as adding 1(x3)-1 \cdot (x-3).
So, we have 6+(1x)+(13)6 + (-1 \cdot x) + (-1 \cdot -3).
This simplifies to 6x+36 - x + 3.

STEP 4

Now, we **combine** the **like terms**, 66 and 33, on the left side.
This gives us 9x9 - x.
So our inequality now looks like 9x>249 - x > 24.

STEP 5

To **isolate** the xx term, we want to get rid of the 99 on the left side.
Since it's added to x-x, we do the opposite operation, which is subtraction!
Subtracting 99 from both sides gives us x>249-x > 24 - 9, which simplifies to x>15-x > 15.

STEP 6

Now, we have x>15-x > 15.
To solve for xx, we need to multiply both sides by 1-1. *Remember* the golden rule: when we multiply or divide both sides of an inequality by a negative number, we *must* **flip** the inequality sign!
So, 1x-1 \cdot -x becomes xx, and 15115 \cdot -1 becomes 15-15.
Flipping the inequality sign gives us x<15x < -15.

STEP 7

The solution to the inequality 6(x3)>246 - (x - 3) > 24 is x<15x < -15.
This means any value of xx less than 15-15 will make the original inequality true!
