Question

Cum se rezolva ex asta 25:5+a%2=25

Answer 1

5+  2a= 25
   100
5+ a : 50 = 25
a:50 = 20
a= 1000

Answer 2

$25:5 + a \% 2 = 25 \\ 5+ \frac{a}{100} \cdot2 = 25 \\ \frac{a}{100} \cdot2 = 25-5 \\ \frac{a}{100} \cdot2 = 20 \\ \frac{a}{100} = 20:2 \\ \frac{a}{100} =10 \\ a = 10 \cdot100 \\ a = 1000$
