Question

suma a doua numere este 95.Aflati numerele stiind ca unul este cu 5 mai mic decat triplul celuilalt.

Answer 1

$x+y=95 \\ y=3x-5 \\ x+3x-5=95 \\ 4x-5=95 \\ 4x=95+5 \\ 4x=100 \\ x=100:4 \\ \boxed{x=25} \\ y=3*25-5 \\ y=75-5 \\ \boxed{y=70}.$

Answer 2

x+y= 95
x= 3y-5

3y-5+y= 95
4y= 95+5
4y=100⇒ y= 100:4⇒y= 25

x+25= 95⇒ x= 95-25=  70;
