resuelve las siguente operaciones porfavor si no saben no escriban porfavor​

Answer 1

9 (a+2) = 9

9a + 18 = 9

9a = 9 - 18

9a = -9

a = -1

16 = 4(m+2)

16 = 4m + 8

16 - 8 = 4m

8 = 4m

8/4 = m

2 = m

8 (z-3) = 24

8z - 24 = 24

8z = 24 + 24

8z = 48

z = 48/8

z = 6

15 = 5 (x-2)

15 = 5x - 10

15 + 10  = 5x

25 = 5x

25/5 = x

5 = x

-4 (k-6) = -4

-4k + 24 = -4

-4k = -4 - 24

-4k = -28

28 = 4k

28/4 = k

6 = k

-18 = 9 (d+1)

-18 = 9d + 9

-18 - 9 = 9d

-27 = 9d

-27/9 = d

-3 = d

6 (b+5) = 18

6b + 30 = 18

6b = 18 - 30

6b = -12

b = -12/6

b = -2

-7 (h-4) = 21

-7h + 28 = 21

-7h = 21 - 28

-7h = -7

7 = 7h

7/7 = h

1 = h

2 (3-t) = -10

6 - 2t = -10

6 + 10 = 2t

16 = 2t

16/2 = t

8 = t

4 (x+5) = 36

4x + 20 = 36

4x = 36 - 20

4x = 16

x = 16/4

x = 4

6 (a+5) = 42

6a + 30 = 42

6a = 42 - 30

6a = 12

a = 12/6

a = 2

4 (6-x) = 20

24 - 4x = 20

24 - 20 = 4x

4 = 4x

4/4 = x

1 = x
