Answer:
Y = 27
Step-by-step explanation:
To find the the value of y when x = 4 simply substitute the given value of x
into the equation and solve for y
Equation given: y - 3x = 15
x = 4 * substitute 4 for x in given equation *
y - 3(4) = 15
Now solve for y
simplify multiplication
y - 12 = 15
Add 12 to both sides
y - 12 + 12 = 15 + 12
y = 27
So we can conclude that when x = 4 y = 27

Answer:
77
Step-by-step explanation:
For each 2 evergreens there are 7 other trees.
Add 2 +7 = 9.
For each 7 non-evergreens there are 9 trees of all types.
The ratio of non-evergreens to total trees is 7/9.
Let x = number of non-evergreens.
7/9 = x/99
9x = 7 * 99
Divide both sides by 9.
x = 7 * 11
x = 77
