Question

suma a doua numere este 395 afla numerele stiind ca triplul jumatatii primului numar micsorat cu 10 este 25 mai mic decat al doilea numar

Answer 1

$a+b=395 \\\\ 3*\frac{a}{2}-10=b-25 \\\\ \frac{3a}{2}-10+25=b \\\\ \frac{3a}{2}+15=b \\\\\\ a+\frac{3a}{2}+15=395 \\\\ a+\frac{3a}{2}=395-15 \\\\ a^{(2}+\frac{3a}{2}=380^{(2} \\\\ 2a+3a=380*2 \\\\ 5a=380*2 \\\\ a=\frac{\not 380 *2}{\not 5} \\\\ a=76*2 \\\\ \boxed{a=152} \\\\ b= \frac{3*\not 152}{\not 2}+15 \\\\ b=3*76+15 \\\\ b=228+15 \\\\ \boxed{b=243}$
