x+0,7 s0, x-12-5

I’m not sure what the exact problem is from your message. It looks like you’re using a decimal comma (0,7) and there might be two expressions like “x + 0,7” and “x - 12 - 5”. Could you confirm the exact problem? For example, you might mean one of these:

1. Equations

• x + 0.7 = 0
• x − 12 = −5 If so, there is no solution (the two equations give x = −0.7 and x = 7 respectively).

2. Inequalities (two conditions)

• x + 0.7 ≤ 0
• x − 12 ≤ −5 Then:
• x ≤ −0.7
• x ≤ 7 Together: x ≤ −0.7 (solution set (−∞, −0.7]).

3. Some other combination, e.g.

• x + 0.7 ≤ 0 and x − 12 ≥ −5 Then:
• x ≤ −0.7
• x ≥ 7 No solution (empty set).

Could you please:

• specify whether you have equations or inequalities (or a system), and
• confirm the exact symbols (e.g., ≤ or =) and whether using a comma for decimals is standard in your locale?

Once you confirm, I’ll show the full solution step by step.
