Question

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

Answer 1

all of these equations except 4n = 48

Explanation:

your equations are

52 = 8n+4

4(2n+1) = 52

4 = 52-8n

4n = 48

n = 6

let's solve these equations!

52 = 8n + 4

48 = 8n

n = 6

4(2n+1) = 52

8n + 4 = 52

8n = 48

n = 6

4 = 52-8n

-48 = -8n

n=6

4n = 48

n = 12

all of these equations simplify to n = 6 except for 4n = 48, so they're all equivalent
