Question

descubra o valor do x

a) x+12=10

b) x-5=6

c) 9x=27

d)
$\frac{x}{4} = 6$

e)16x=-32

f)0,7x=1,4

g)-5x=30

h)
$\frac{x}{ - 2} = 5$

i)
$\frac{x}{ - 4} = - 6$
​

Answer 1

Olá...

a)

x + 12 = 10

x = 10 - 12

x = - 2

b)

x - 5 = 6

x = 6 + 5

x = 11

c)

9x = 27

x = 27/9

x = 3

d)

x/4 = 6

x = 6 . 4

x = 24

e)

16x = - 32

x = - 32/16

x = - 2

f)

0,7 x = 1,4

x = 1,4/0,7

x = 2

g)

- 5x = 30 ⇒( - 1)

5x = - 30

x = - 30/5

x = - 6

h)

x/-2 = 5

x = 5 . ( - 2)

x = - 10

i)

x/-4 = - 6

x = - 6 . (- 4)

x = 24

Bons estudos.

Answer 2

• assunto; equaçao do 1 grau.

a) x = 10 - 12 = -2

b) x = 6 + 5 = 11

c) x = 27/9 = 3

d) x = 4 * 6 = 24

e) x = -32/16 = -2

f) x = 1.4/0.7 = 2

g) x = -30/5 = -6

h)  x = -2*5 = -10

i)  x = -4 * -6 = 24
