a) x + 2 = +6
b) x + 8 = +5
c) x - 3 = +6
d) x - 3 = +6
e) x - 7 = -1
f) x + 2 = -9
g) x + 7 = +7

Me ajudemmm!

Answer 1

Explicação passo-a-passo:

Oiee! <3

A)

x + 2 = 6

x = 6 - 2

x = 4

B)

x + 8 = 5

x = 5 - 8

x = -3

C)

x - 3 = 6

x = 6 + 3

x = 9

D)

x - 3 = 6

x = 6 + 3

x = 9

E)

x - 7 = -1

x = -1 + 7

x = 6

F)

x + 2 = -9

x = -9 - 2

x = -11

G)

x + 7 = 7

x = 7 - 7

x = 0

H)

x - 6 = 6

x = 6 + 6

x = 12

i)

x + 8 = 0

x = 0 - 8

x = -8

J)

x - 11 = -20

x = -20 + 11

x = -9

Espero ter ajudado, bom estudo! S2

Answer 2

$a)$ $x + 2 = +6$

$x = + 6 - 2$

$x = +4$

$b) x + 8 = +5$

$x = 5 - 8$

$x = -3$

$c) x - 3 = +6$

$x = + 6 + 3$

$x = +9$

$d) x - 3 = +6$

$x = + 6 + 3$

$x = + 9$

$e) x - 7 = -1$

$x = -1 + 7$

$x = +6$

$f) x + 2 = -9$

$x = - 9 - 2$

$x = -11$

$g) x + 7 = +7$

$x = + 7 - 7$

$x = 0$

$h) x - 6 = +6$

$x = +6 + 6$

$x = +12$

$i) x + 8 = 0$

$x = 0 - 8$

$x = -8$

$j) x - 11 = -20$

$x = -20 + 11$

$x = - 9$
