Question

son ecuaciones de 1er nivel doy coronita por favor ​

Answer 1

Explicación paso a paso:

b)

a - 3 = 12

a = 12 + 3

a = 15

c)

y + 8 = 16

y = 16-8

y = 8

d)

b - 10 = 5

b = 5+10

b = 15

e)

m - 7 = 13

m = 13+7

m = 20

f)

h + 6 = 18

h = 18-6

h = 12

g)

k - 2 = 23

k = 23+2

k = 25

h)

f + 9 = 24

f = 24-9

f = 15

i)

x +2.5 = 5

x = 5-2.5

x = 2.5

j)

a - 1.6 = 3

a = 3+1.6

a = 4.6

k)

y +3.9 = 5.1

y = 5.1-3.9

y = 1.2

l)

b - 4.3 = 2.7

b = 2.7+4.3

b = 7
