Hmmm. So perimeter is all sides added together, can you write an equation for the perimeter of the first one?

p = 2y + 1x is that right?

Yep but you know the perimeter so go ahead and put that in to x+2y=14 now the second one

3x + 5/4y = 21 is that right?

Forgot a side 3x+(5/4)y+(5/4)y=21 which simplifies to 3x+(5/2)y=21 so now we have two equations 3x+(5/2)y=21 x+2y=14 any idea how to solve?

You could. Multiply the second equation by 3 and then add the two equations together
