x+0,7 s0, x-12-5
I’m not sure how to read your notation. Do you mean a system of inequalities something like:
- x + 0,7 ≤ 0
- x − 12 ≤ −5
(where the comma is a decimal comma, as used in Polish/russian notation, and “≤” is the sign you intended)?
If that’s the case, here’s how to solve:
- x + 0,7 ≤ 0 → x ≤ −0,7
- x − 12 ≤ −5 → x ≤ 7
Intersection: x ≤ −0,7 So the solution set is (−∞, −0,7].
If you meant a slightly different second part (for example x − 12 − 5 ≤ 0, which is x ≤ 17), the result still ends up x ≤ −0,7 in this setup. But I need the exact signs to be sure.
Could you please confirm the exact inequalities (the signs and whether there are two separate inequalities or a single expression)? If you paste the problem with clear signs (e.g., using ≤, ≥, = and parentheses), I’ll solve it precisely. Also, if you prefer, I can convert to decimal points (0.7 instead of 0,7).
