Answer 1

Ecuaciones de primer grado

m - 7 = 13

m = 13 + 7

m = 20

Comprobación:

m - 7 = 13

20 - 7 = 13

13 = 13

n + 6 = 18

n = 18 - 6

n = 12

Comprobación:

n + 6 = 18

12 + 6 = 18

18 = 18

k - 2 = 23

k = 23 + 2

k = 25

Comprobación:

k - 2 = 23

25 - 2 = 23

23 = 23

f + 9 = 24

f = 24 - 9

f = 15

Comprobación:

f + 9 = 24

15 + 9 = 24

24 = 24

x + 2.5 = 5

x = 5 - 2.5

x = 2.5

Comprobación:

x + 2.5 = 5

2.5 + 2.5 = 5

5 = 5

a - 1.6 = 3

a = 3 + 1.6

a = 4.6

Comprobación:

a - 1.6 = 3

4.6 - 1.6 = 3

3 = 3

y + 3.9 = 5.1

y = 5.1 - 3.9

y = 1.2

Comprobación:

y + 3.9 = 5.1

1.2 + 3.9 = 5.1

5.1 = 5.1

b - 4.3 = 2.7

b = 2.7 + 4.3

b = 7

Comprobación:

b - 4.3 = 2.7

7 - 4.3 = 2.7

2.7 = 2.7
