35/y + 6 = 11

First, subtract 6 from both sides:

35/y = 5

Now, multiply both sides by y to isolate y:

y = 35/5
y = 7

So, y = 7.

50 - 9a = 23

First, subtract 50 from both sides:

-9a = -27

Now, divide by -9 to solve for a:

a = -27 / -9
a = 3

So, a = 3.

$4+x$ / 8 = 9

First, multiply both sides by 8 to get rid of the fraction:

4 + x = 72

Now, subtract 4 from both sides:

x = 68

So, x = 68.
