Answer: X = 2
Step-by-step explanation:
Answer: X=4
Step-by-step explanation:
Pulling out like terms :
1.1 Pull out like factors :
2x - 8 = 2 • (x - 4)
Equation at the end of step 1 :
Step 2 :
Equations which are never true :
2.1 Solve : 2 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation :
2.2 Solve : x-4 = 0
Add 4 to both sides of the equation :
x = 4
One solution was found :
x = 4
To add or subtract rational expressions with unlike denominators, first find the LCM of the denominator. The LCM of the denominators of fraction or rational expressions is also called least common denominator, or LCD. Write each expression using the LCD.

Answer:
Part a) The constant of variation is 
or 
Part b) 
Step-by-step explanation:
Part a) Find the constant of variation.
we know that
The simple interest formula is equal to
In this linear direct variation the constant r represent the constant of proportionality
where
I is the Interest Value
P is the Principal amount of money to be invested
r is the rate of interest
t is Number of Time Periods
in this problem we have
substitute the values and solve for r
Part b) what will the interest be after 3 years
in this part we have
substitute the values
