Ayudenme Porfavor, Les Doy Coronita xd​

Answer 1

Respuesta:

a)

$7 + 4 + x - 6 = 5 + 4 \\ 11 + x - 6 = 9 \\ 5 + x = 9 \\ x = 9 - 5 \\ x = 4$

b)

$12 - 8 + y - 3 = 21 + 4 \\ 4 + y - 3 = 25 \\ 1 + y = 25 \\ y = 25 - 1 \\ y = 24$

c)

$3 + 2a - 8 - 5 = 25 + 3 \\ 3 + 2a - 13 = 28 \\ - 10 + 2a = 28 \\ 2a = 28 + 10 \\ 2a = 38 \\ a = 38 \div 2 \\ a = 19$

d)

$20 + 4 - 10 + 4p = 65 - 34 \\ 24 - 10 + 4p = 31 \\ 14 + 4p = 31 \\ 4p = 31 - 14 \\ 4p = 17 \\ p = 17 \div 4 \\ p = 4.25$
