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.
