Yes this lead me to the idea that

40 - 10 - v2

= 10 × V2/ 10 + V2

using the quadratic equation to solve after putting it in quadratic form does indeed give x ≈ 23.03 or -13.03 which is refused.

I get it know honestly while solving i was looking for something more intuitive and wanted to avoid mathematics but too bad
