Question

Solve -3x-6>4x+8 please

Answer 1

[tex]\bf{-3x-6 > 4x+8}[/tex]

Subtract 4x on both sides.

[tex]\bf{-3x-6-4x > 8}[/tex]

Combine -3x and -4x to get -7x.

[tex]\bf{-7x-6 > 8 }[/tex]

Add 6 to both sides.

[tex]\bf{-7x > 8+6 }[/tex]

Add 8 and 6 to get 14.

[tex]\bf{-7x > 14 }[/tex]

Divide both sides by -7. Since -7 is < 0, the inequality direction is changed.

[tex]\bf{x < \dfrac{14}{-7} }[/tex]

Divide 14 by -7 to get -2.

[tex]\bf{x < -2 \ \ \to \ \ \ Answer}[/tex]

Answer 2

Hi student, let me help you out!

.......................................................................................................

Let's solve this inequality by following these steps:

- Add 6 to both sides.
- Subtract 4x from both sides.
- Solve for x.

Step 1: Add 6 to both sides: [tex]\pmb{-3x-6+6 > 4x+8+6}[/tex].

Upon simplifying this, we obtain [tex]\pmb{-3x > 4x+14}[/tex].

Step 2. Subtract 4x from both sides: [tex]\pmb{-3x-4x > 4x-4x+14}[/tex].

Upon simplifying, we obtain [tex]\pmb{-7x > 14}[/tex].

Step 3. Divide both sides by -7.

Upon carrying this out, we obtain [tex]\pmb{x < -2}[/tex].
