Question

x+y=96
x÷y=5
_______
x=?
y=?

​

Answer 1

Explicație pas cu pas:

x+y=96

x:y=5 => x = 5y

5y + y = 96

6y = 96

y = 96 : 6

y = 16

x = 16 × 5

x = 80

Answer 2

x + y = 96

x : y = 5

x = 5 × y

5 × y + y = 96

6 × y = 96

y = 96 : 6

y = 16

x = 5 × 16

x = 80

Verificare :

80 + 16 = 96

80 : 16 = 5
