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.

welshfella · Answer

There are 2 expressions in terms of w  and they both equal p.
So what can you say about the relation between these 2 expressions?

welshfella · Answer

How are they realated?   > , < or =?

nuccioreggie · Answer

its A @welshfella

welshfella · Answer

yes 
they are equal  because they are both equal to p.
In the US I think its called the transitive property of equality.
