Answer:
Depends, is it asking X times 7 is 16; X plus 7 = 16; or X divided by 7 = 16?
Step-by-step explanation:

Answer:
Step-by-step explanation:
To write the expression as a radical use the form to convert.
We have:
(d) 4x + 6y = 9 <=> y = -2/3 x + 3/2 (d') -3x + ny = 8 <=> y = 3/n x + 8/n
So: (d) ⊥ (d')
=> -2/3 × 3/n = -1
=> -2/n = -1
=> n = -2/-1
=> n = 2
