Solve -3x-6>4x+8 please
WARRIOR [948]

Hi student, let me help you out!

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

Let's solve this inequality by following these steps:

  1. Add 6 to both sides.
  2. Subtract 4x from both sides.
  3. Solve for x.

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

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

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

Upon simplifying, we obtain \pmb{-7x > 14}.

Step 3. Divide both sides by -7.

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

\ddot\bigstar Remember this...

Hope this helped you out, ask in comments if any queries arise.

Best Regards!
