Question

8d + 30 = 54
3a – 7 = 20
5n + 10 = 55
6x – 2 = 4
7m + 25 = 46
4c – 5 = 15
9z + 2 = 20

Answer 1

Explicación paso a paso:

• 8d + 30 = 54

8d = 54 – 30

d = 24/8

d = 3

• 3a – 7 = 20

3a= 20+7

a= 27/3

a = 9

• 5n + 10 = 55

5n= 55 – 10

n= 45/5

n = 9

• 6x – 2 = 4

6x = 4 + 2

x= 6/6

x = 1

• 7m + 25 = 46

7m = 46 – 25

m = 21/7

m = 3

• 4c – 5 = 15

4c = 15 + 5

c = 20/4

c = 5

• 9z + 2 = 20

9z = 20 – 2

z= 18/9

z = 2
