Question

mim ajudem é pra hoje​

Answer 1

a)

2x = 30

x = 30 / 2

x = 15

b)

y + 12 = 15

y = 15 - 12

y = 3

c)

p - 5 = 18

p = 18 + 5

p = 23

d)

m / 3 = 7

m = 7 x 3

m = 21

e)

x + 12 = 4

x = 4 - 12

x = - 8

f)

5k = - 5

k = - 5 / 5

k = - 1

g)

2n + 1 = 15

2n = 15 - 1

2n = 14

n = 14 / 2

n = 7

h)

( y + 1 ) = 6

2

y + 1 = 6 . 2

y + 1 = 12

y = 12 - 1

y = 11
