Hello, I have been working on this for many days and I have been struggling for those many days. Math hasn't always been something I am good at so thank you for helping me.
Becky and Cathy are sisters. Becky is four years older than Cathy. The following shows how Becky's age, y, changes as Cathy's age, x, changes.
Which equation shows this relationship?
A.
y + 4 = x
B.
y = x + 4
C.
4y = x
D.
y = 4x
Becky's age: y
Cathy's age: x
<=====> "Becky is four years older than Cathy"
It's as SIMPLE as that!!
