Question

8th grade math (easy) Medal and Fan!!!
/just have to find where the first error is/ ..Systems of Equations..

Answer 1

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? (1 point)


Step 1
Step 2
Step 3
Step 4

Answer 2

a number is left out in the add - Can you see which number it is?

Answer 7

yes

Answer 8

4!

Answer 9

thats correct

Answer 10

ohh, ok so the answer is Step 3?

Answer 11

yes
it should be
-4m + 4m = -32 - 8n + 4 + 4n

Answer 12

oh ok, thanks for explaining. I like when people explain instead of just giving me the answer. Im ur fan now, and I gave u a medal!

Answer 13

ty yw
Yes giving the answer doesn't teach you much.
