240:(x+3)-5=7

First, we simplify the left side of the equation:
240 / (x + 3) - 5 = 7

Next, we isolate the term with the variable x:
240 / (x + 3) = 7 + 5
240 / (x + 3) = 12

Then, we cross multiply:
240 = 12(x + 3)
240 = 12x + 36

Next, we isolate the variable x:
12x = 240 - 36
12x = 204
x = 204 / 12
x = 17

Therefore, the solution to the first equation is x = 17.

16*(11 - x/8) = 64

We first simplify the second equation:
16*(11 - x/8) = 64

Next, we distribute the 16 into the parentheses:
176 - 2x = 64

Then, we isolate the term with the variable x:
-2x = 64 - 176
-2x = -112

Finally, we solve for x:
x = -112 / -2
x = 56

Therefore, the solution to the second equation is x = 56.
