The work of a student to solve a set of equations is shown below:
equation 1: m=8+2n
equation 2: 4m =4+4n

step 1: -4(m)=-4(8+2n)
4m = 4 + 4n

step 2: -4m=-32-8n
4m = 4 +4n

step 3: -4m+4m= -32 - 8n + 4n

step 4: 0= -32 - 4n

step 5: n=-8

in which step did the student first make an error?

step 3

Step-by-step explanation:

just took the quiz and i got it right by answering step 3

step-by-step explanation:

. your answer will contain x - and y -terms. (1 point) x ( ¿¿ 2 − 7 ) 2 +( y 2 − 9 ) 2 √ ¿ 12. what is the distance from the directrix (the crocodile river) to the point ( x , y )? write this equation. your answer will contain a y -term.

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
