Peter is 2 years older than Winnie. Peter's age is 16 years less than seven times Winnie's age. The equations below model the relationship between Peter's age (p) and Winnie's age (w): p = w + 2
p = 7w − 16

Which is a possible correct method to find Peter's and Winnie's ages? (5 points)

a
Solve w + 2 = 7w − 16 to find the value of w.

b
Solve p + 2 = 7p − 16 to find the value of p.

c
Write the points where the graphs of the equations intersect the x axis.

d
Write the points where the graphs of the equations intersect the y axis.
