The rate of change in this pattern is 2:1 comparing the change in 'y' to the change in 'x'.. this means that if you go form 33 to 51 ( an increase of 18), then the the increase from 16 to ? will be 9. Therefore, ? = 16 + 9 or 25
? = 25

y = 7 - x
Step-by-step explanation:
Let y be the length of the other section
x + y = 7
y = 7 - x
of course, the width of the saw kerf (k) should also be accounted for so a carpenter would figure it as
y = 7 - x - k
