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.

Respuesta :

substitute P on the second equation so now it looks like...
w+2 = 7w-16. from there we can see that w = 3
So basically, the first answer.
Solve w + 2 = 7w - 16 to find the value of w.
