Answer 2

 

Voi nota cele 2 ecuatii cu a) si b).

.

$\displaystyle\bf\\a)\\3x+1,\!5=2x+3\\3x-2x=3-1,\!5\\\boxed{\bf~x=1,\!5}\\\\\\b)\\0,\!0(6)-0,\!25=x\\x=0,\!0(6)-0,\!25\\\textbf{Transformam fractiile zecimale in fractii ordinare.}\\\\x=\frac{6}{90}-\frac{25}{100}\\\\x=\frac{^{4)}1}{~15}-\frac{^{15)}1}{~~~4}\\\\x=\frac{4}{60}-\frac{15}{60}\\\\x=\frac{4-15}{60}\\\\x=\frac{-11}{~60}\\\\\boxed{\bf~x=-\frac{11}{60}}$
