Question

1) Resuelve las siguientes ecuaciones:
a) 40 +3.X = 58
b) (X+3). 2 = 8
c) 2.x + 16 = x + 18
d) x2 + 20 = 56
e) 4.x + 10 = 2.x + 30​

Answer 1

Respuesta:

a) 40 + 3.x = 58

40 + 3x = 58

3x = 58 - 40

3x = 18

x = 18/3

x = 6

b) (x+3).2 = 8

2x + 6 = 8

2x = 8 - 6

2x = 2

x = 2/2

x = 1

c) 2.x + 16 = x + 18

2x + 16 = x + 18

2x - x = 18 - 16

x = 2

d) x.2 + 20 = 56

2x = 56 -20

2x = 36

x = 36/2

x = 18

e) 4.x + 10 = 2.x + 30

4x + 10 = 2x + 30

4x - 2x = 30 - 10

2x = 20

x = 20/2

x = 10
