95:5=19 a
19+1=20 b
19+2=21 c
19+3=22 d
19+4=23 e

Answer 2

x = a
y = a + 1
z = a + 1 + 1
v = a + 1 + 1+ 1
t = a + 1 +1 +1 +1
x + y + z + v + t = 105
a  + a + 1  + a + 1 + 1  + a + 1 + 1 + 1 +a + 1 + 1 + 1 + 1= 105
5a = 105 - 10
5a = 95
a = 95 : 5
a = 19
x = 19
y = 20
z = 21
v = 22
t = 23
verificam
19 + 20 + 21 + 22 +23=105
