Answer:
x=7
Step-by-step explanation:
<span>You are given the equation:
</span><span>(x - 3)/3 = x + 3
The first step to solving is getting rid of the denominator on the left-hand side of the equation. You get rid of denominators by multiplying both sides of the equation by the reciprocal. The denominator here is 3, so you'd multiply both sides of the equation by 3. That yields the equation in Step 1.

Since you are multiplying both sides of the equation by a quantity, you are using the Multiplication Property.
Answer:
D) Multiplication Property
The quantity of liters of the 2% and 66% solutions should you mix together is 4.75 and 11.25 liters.
let
- x = liters of 2% solution
- y = liters of 66% solution
x + y = 16
0.02x + 0.66y = 0.47 × 16
from (1)
x = 16 - y
Substitute into (2)
0.02x + 0.66y = 0.47 × 16
0.02(16 - y) + 0.66y = 7.52
0.32 - 0.02y + 0.66y = 7.52
- 0.02y + 0.66y = 7.52 - 0.32
0.64y = 7.20
y = 7.20/0.64
y = 11.25 liters
Substitute y = 11.25 liters into (1)
x + y = 16
x + 11.25 = 16
x = 16 - 11.25
x = 4.75 liters
