Answer:
x = -9
Step-by-step explanation:
6 - 2/9x = 8
Subtract 6 from each side
6-6 - 2/9x = 8-6
-2/9 x = 2
Multiply each side by -9/2 to isolate x
-9/2 * -2/9x = 2*-9/2
x = -9
Uhhh, kind of an estimated guess but I got $7426.30
Yes for the first one, yes for the second one, and yes for the third one although your subtraction equation had the wrong year (its not 1847 its 1846) but the answer was right, 65.

Step-by-step explanation:
A.C
B.2w + 2(w + 3) = 72
2w + 2w + 6 = 72
4w + 6 = 72
4w = 72 - 6
4w = 66
w = 16.5
