Question

The work of a student to solve a set of equations is shown:

Equation 1: m = 8 + 2n
Equation 2: 4m = 4 + 4n

Step 1: –4(m) = –4(8 + 2n) [Equation 1 is multiplied by –4.]
4m = 4 + 4n [Equation 2]
Step 2: –4m = –32 – 8n [Equation 1 in Step 1 is simplified.]
4m = 4 + 4n [Equation 2]
Step 3: –4m + 4m = –32 – 8n + 4n [Equations in Step 2 are added.]
Step 4: 0 = –32 – 4n
Step 5: n = –8


In which step did the student first make an error?


Step 1
Step 2
Step 3
Step 4

Answer 1

looks like the 4 got dropped in step 3
who wrote this please?

Answer 2

this is the nonsense work i have to do. I don't know who wrote this by the way.

Answer 3

is it an on line class?

Answer 4

and if so, what system?

Answer 5

ya and its brainhoney

Answer 6

Equation 1: m = 8 + 2n
Equation 1: m = 8 + 2n
try to find solution of these 2 equations
don't look at the multiple choices yet
if you know how to solve these type of questions then you willll be able to find mistakes

Answer 7

@Lianna98 Bavel, brainhoney??? Module 8 practice test?
