Question

1. Resuelve las siguientes ecuaciones:
a) x - 4 = 3
b) x - 2 = -5
c) x+5=8
d) x + 6 = -2
e) 4x = 16
A-ñ2x=8
g) x = 5
h) 4x = 6

Answer 1

Respuesta:

a) x = 7

b) x = -3

c) x = 3

d) x = -8

e) x = 4

g) x = 15

h) x = 1,5

Explicación paso a paso:

e) 4x = 16

x = 16/4

x = 4

g) 1/3x = 5

x = 5(3)/1

x = 15

h) 4x = 6

x = 6/4

x = 3/2

x = 1,5

Answer 2

a)

x - 4 = 3

x = 3 + 4

x = 7

b)

x - 2 = - 5

x = - 5 + 2

x = - 3

c)

x + 5 = 8

x = 8 - 5

x = 3

d)

x + 6 = - 2

x = - 2 - 6

x = - 2

e)

4x = 16

4x ÷ 4 = 16 ÷ 4

x = 16 ÷ 4

x = 4

f)

2x = 8

2x ÷ 2 = 8 ÷ 2

x = 8 ÷ 2

x = 4

g)

x = 5

x - 5 = 5 - 5

x - 5 = 0

h)

4x = 6

4x ÷ 4 = 6 ÷ 4

x = 6 ÷ 4

x = 3/2 = 1,5

1/3x = 5

3 × 1/3 x = 3 × 5

x = 3 × 5 =

x = 15
