2x +6>12 x+4

It looks like you meant the inequality 2x + 6 > 12x + 4. Here’s the solution:

• 2x + 6 > 12x + 4
• Subtract 2x: 6 > 10x + 4
• Subtract 4: 2 > 10x
• Divide by 10: x < 1/5

Solution: x ∈ (-∞, 1/5)

If you meant something else (for example, two separate inequalities), let me know and I’ll solve those too.
