Question

AYUDA :( PORFA :( TA DIFICIL​

Answer 1

Respuesta:

c) 27

S: Susana

S+ $\frac{S}{3}$ = 36

$\frac{3S}{3} + \frac{S}{3}$ = 36

$\frac{3S + S}{3}$ = 36

3*$\frac{4S}{3}$ = 3*36

4S = 108

S = 27

d) 2 años

26 + x = 4*(5+x)

26 + x = 20 + 4x

26 - 20 = 4x - x

6 = 3x

2 = x

e) Roberto = 30, Martha = 10

X + 4 +3x+4 = 48

4x = 48 - 8

x = 40/4

x = 10
