Answer:
4-3x=x+10
Step-by-step explanation:
4- (four less)
3x (3 times a number)
= (is the same as)
x (the number)
+10 (plus ten)

Let's call the number of rows 'R' . (Clever ?)
There are (3x -2) trees in each row, and there are 'R' rows,
so the total number of trees is [ R times (3x-2) ].
But the problem told you that the total number of trees is (24x-16).
So
R(3x - 2) = (24x - 16)
For a quick, happy ending, how about factoring '8' out of the right side:
R(3x - 2) = 8(3x - 2)
Is it jumping out at you yet ?
If not, then divide each side by (3x - 2) :
<em> <u> R = 8</u></em>
There are eight (8) rows of trees.

The system of linear equations that relates x and y:
x= 15 + y
5 x = 2 y+ 525
We will solve this system using substitution method:
5(15 + y)=2 y + 525
75 + 5 y = 2 y + 525
5 y - 2 y = 525 - 75
3 y = 450, y = 450 : 3 y = 150
x = 15 + y x = 15 + 150 x = 165
