12. (08.05 hc)
the work of a student to solve a set of equations is shown:
equation 1: m = 8 + 2n
equation 2: 3m = 4 + 4n
step 1: –3(m) = –3(8 + 2n) [equation 1 is multiplied by –3.]
3m = 4 + 4n [equation 2]
step 2: –3m = –24 – 6n [equation 1 in step 1 is simplified.]
3m = 4 + 4n [equation 2]
step 3: –3m + 3m = –24 – 6n + 4n [equations in step 2 are added.]
step 4: 0 = –24 – 2n
step 5: n = –12
in which step did the student first make an error? (1 point)
step 4
step 3
step 2
step 1

variable g is 8 more than variable w. variable g is also 4 less than w. which pair of equations best models the relationship between g and w? (1 point)
g= w – 8
g = w + 4
w = 8g
w = g – 4
g= w + 8
g = w – 4
w = 8g
w = g + 4
