Din păcate, am avut o problemă calcul a datelor introduse.
5.a) [tex] 2\frac{5}{6} = \frac{x}{12} [/tex]
[tex] \frac{17}{6} = \frac{1}{12}x [/tex]
[tex] \frac{1}{12}x= \frac{17}{6} [/tex]
[tex]12*( \frac{1}{12}x)=12*( \frac{17}{6})[/tex]
x=34
b) [tex]3* \frac{x}{x+1} = \frac{19}{5} [/tex]
[tex] \frac{3x}{x+1} = \frac{19}{5} [/tex]
3x*(5)=19*(x+1)
15x=19x+19
15x−19x=19x+19−19x−4x=19
[tex] \frac{-4x}{-4} = \frac{19}{-4} [/tex]
[tex]x= \frac{19}{-4} [/tex]
