8x + 4 = 5x - 11
Subtract 5x from both sides:
3x + 4 = -11
Subtract 4 from both sides:
3x = -15
Divide both sides by 3:
x = -5
Answer : x = -5

Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
f(x) = 5x + 7
g(x) = 3x - 1
<u>Step 2: Find</u>
- Substitute in functions: f(g(x)) = 5(3x - 1) + 7
- [Distributive Property] Distribute 5: f(g(x)) = 15x - 5 + 7
- [Addition] Combine like terms: f(g(x)) = 15x + 2
The variable a cannot be zero because that would make -9a = zero and 8 divided by zero is indeterminate.

a.
60 ounces = 3 pounds
So no, you don’t have as much fruit as you need.
b.
60 ounces —> 3 pounds
X ounces —> 4 pounds
Cross product :
(60 x 4) / 3 —> 240/3 = 80
So in order to have 4 pounds of fruits, you need 80 ounces of fruits.
You already have 60 ounces of fruits.
X + 60 = 80
80 - 60 = X
20 = X
You need 20 more ounces to have 4 pounds of fruits.
