Question

me ayudan con la ecuación ​

Answer 1

Respuesta:

2(x+4) = 1+(3)²

2x+8 = 1+9

2x+8 = 10

(2x/2)+(8/2) = (10/2)

x+4 = 5

x+4-4 = 5-4

x = 1

2(x+4) = (1+3)²

2x+8 = 4²

2x+8 = 16

(2x/2)+(8/2) = (16/2)

x + 4 = 8

x+4-4 = 8-4

x = 4

2x-4 = 1+3²

2x-4 = 1+9

2x-4 = 10

2x-4+4 = 10+4

2x = 14

2x/2 = 14/2

x = 7

2x-4 = (1+3)²

2x-4 = 16

2x-4+4 = 16+4

2x = 20

2x/2 = 20/2

x = 10
