Q: Kevin is 4 years older than Margaret.
Next year Kevin will be 2 times as old as Margaret.
How old is Kevin?
A:
Solution
Denote as  Kevin's present age.
Then Margret's present age is .

Next year Kevin will be  years old, and Margaret will be  years old.

Since next year Kevin will be 2 times as old as Margaret, you can write the equation
.

Solve this equation by simplifying it, step by step:

   (after brackets opening at the right side)
   (after moving variable terms to the right and constant terms to the left)
             (after combining like terms)

Thus, you got that Kevin's present age is  years.

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
