Question

Select all the equations that are equivalent. 52 = 8n + 4 4(2n + 1) = 52 4 = 52 – 8n 4n = 48 n = 6

Answer 1

52 = 8n + 4

4(2n + 1) = 52

4 = 52 – 8n

n = 6

Explanation:

52 = 8n + 4

52 - 4 = 8n

48 = 8n

n = 48/8

n = 6

4(2n + 1) = 52

8n + 4 = 52

8n = 52 - 4

8n = 48

n = 48/8

n = 6

4 = 52 – 8n

4 - 52 = -8n

-48 = -8n

n = -48/-8

n = 6

4n = 48

n = 48/4

n =12

n = 6

52 = 8n + 4 is equivalent to 4(2n + 1) = 52 is equivalent to 4 = 52 – 8n is equivalent to n = 6
