a
4f + 1= 3f
b
4f = 3f + 5
c
4f + 5 = 3f + 1
d

2-Wilson is 6 years older than Mary. Wilson's age is 10 years less than five times Mary's age. The equations below model the relationship between Wilson's age (w) and Mary's age (m):
w = m + 6
w = 5m − 10
Which is a possible correct method to find Wilson's and Mary's ages? (5 points)
a
Solve w + 6 = 5w − 10 to find the value of w.
b
Write the points where the graphs of the equations intersect the x axis.
c
Solve m + 6 = 5m − 10 to find the value of m.
d
Write the points where the graphs of the equations intersect the y axis.
3-Variable c is 9 more than variable w. Variable c is also 3 less than variable w. Which pair of equations best models the relationship between c and w? (5 points)
a
c = w − 9
c = 4w + 3
b
c = w + 9
c = w − 3
c
w = c + 9
w = c − 3
d
w = c − 9
w = 4c + 3
