You simply have to sum the two fraction together to get the total amount of occupied plot. To do so, multiply both numerator and denominator of each fration by the same number, so that they end up having the same denominator.
You can multiply both numerator and denominator of 1/8 by 3 to get 3/24. Similarly, you can multiply both numerator and denominator of 1/6 by 4 to get 4/24.
Now we can easily sum the two fractions together:
So, if 7 parts out of 24 are occupied, it means that there are 
parts left for other crops. So, the answer is 17/24.
Sin is x
tan is y
Hope this helped☺☺
I did some math and i got this
x = -2
The "product" of two numbers means you multiply them.
So, you are multiplying (8-n), where n = "a number," by 7.
Then, when you decrease (subtract) this product by 5, you get 40.
So the whole thing looks like
7(8-n) - 5 = 40.
What you would do is you would keep subtracting (I recommend a calculator for this task) from both accounts until you get an equal amount for each. You would also have to record this down that way you know each time what you got. (And please do not put the calculator part). Really hope this helps!!!
