I got 1808 is your multiple choice wrong?
-16 = 8x/5......8x/5 is the same as 8/5(x)
-16 = (8/5)x...divide both sides by 8/5

-16 * 5/8 = x
-80/8 = x
-10 = x <===

Answer:
B
Step-by-step explanation:
4x + 11y = 3
11y = -4x + 3
y = -4/11x + 3/11
perp. 11/4
y - 7 = 11/4(x - 2)
y - 7 = 11/4x - 11/2
y -14/2= 11/4x - 11/2
y = 11/4x + 3/2
