Por favor me ajudem
pleaseeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee​

Answer 1

Resposta:

a) x + 5 = 8

x+5-5=8-5

x = 3

b) x – 4= 3

X = 7

c) x + 6 = 5

x = -1

-

d) x-3=-7

x-3+3=-7+3

x= -4

e) x +9= -1

x = -10

f) x + 28 = 11

x = -17

g) x – 109 = 5

X = 114

i) 10 = x + 9

10-9=x+9-9

x= 1

j) 15 = x + 20

15-20= x+20-20

x= -5

L) 4 = x - 10

4+10=x-10+10

x= 14

m) 7 = x + 8

7-8= x + 8-8

x= -1

n) 3 = x + 10

3-10=x + 10-10

x= -10

Espero ter ajudado.

tenham uma boa tarde.

Answer 2

a)

$x + 5 = 8$

$x = 8 - 5$

$x = 3$

b)

$x - 4 = 3$

$x = 3 + 4$

$x = 7$

c)

$x + 6 = 5$

$x = 5 - 6$

$x = - 1$

d)

$x - 3 = - 7$

$x = - 7 + 3$

$x = - 4$

e)

$x + 9 = - 1$

$x = - 1 - 9$

$x = - 10$

f)

$x + 28 = 11$

$x = 11 - 28$

$x = - 17$

g)

$x - 109 = 5$

$x = 5 + 109$

$x = 114$

h)

$x - 39 = - 79$

$x = - 79 + 39$

$-x = - 40$

i)

$10 = x + 9$

$10 - 9 = x$

$x = 1$

$1 = x$

j)

$15 = x + 20$

$15 - 20 = x$

$x = - 5$

$- 5 = x$

l)

$4 = x - 10$

$4 + 10 = x$

$x = 14$

$14 = x$

m)

$7 = x + 8$

$7 - 8 = x$

$x = - 1$

$- 1 = x$

n)

$3 = x + 10$

$3 - 10 = x$

$x = - 7$

$- 7 = x$
