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?

solve w + 2 = 7w − 16 to find the value of w.
solve p + 2 = 7p − 16 to find the value of p.
write the points where the graphs of the equations intersect the x axis.
write the points where the graphs of the equations intersect the y axis.
