Question

cuanto es:
11n+3 = 5n+27
5x+1 = 21+3x
3p+2+5p = 4p+16+2p
(ayudenme porfavor no lo entiendo nada)

Answer 1

• 11n + 3 = 5n + 27

11n - 5n = 27 - 3

11n - 5n

6n = 27 - 3n

6n = 24

6n ÷ 6 = 24 ÷ 6

n = 24 ÷ 6

n = 4

• 5x + 1 = 21 + 3x

5x - 3x + 1 = 21

5x - 3x = 21 - 1

5x - 3x

2x = 21 - 1

2x = 20

2x ÷ 2 = 20 ÷ 2

x = 20 ÷ 2

x = 10

• 3p + 2 + 5p = 4p + 16 + 2p

5p + 3p

8p + 2 = 4p + 16 + 2p

4p + 2p

8p + 2 = 6p + 16

80 - 6p + 2p = 16

8p - 6p = 16 - 2

8p - 6p

2p = 16 - 2

2p = 14

2p ÷ 2 = 14 ÷ 2

p = 14 ÷ 2

p = 7
