125% : \(x\) + 234 = 7,75
125% : \(x\) = 7,75 - 234
125% : \(x\) = - 226,25
\(x\) = 125% : (- 226,25)
\(x\) = - \(\dfrac{1}{181}\)
125% : x + 234 = 7,75
\(\dfrac{5}{4}\) : x + 234 = 7,75
\(\dfrac{5}{4}\) : x = 7,75 - 234
\(\dfrac{5}{4}\) : x = -226,25
x = \(\dfrac{5}{4}\) : (-226,25)
x = \(\dfrac{1}{181}\)
