To solve, we need to subtract from these two fractions. In order to do this, we will change one of them to have the same denominator as the other.
We have 5/14 and 1/7
Let us change 1/7
Multiply 2/2 (a form of 1 so it does not change the value of the fraction)
2/2 • 1/7 = 2/14
Now subtract from 5/14
5/14 - 2/14 = 3/14

Set the equation to 125.
15x+50= 125
Subtract 50.
15x= 75
Divide by 15 into both sides.
x= 5

(x² + 16)(x² - 16)
= (x²)² - 16²
= x⁴ - 256
Answer: 
Step-by-step explanation:
Having the following equation given in the exercise:
You can solve for "a" following this procedure:
1. You can apply the Subtraction property of equality and subtract 
from both sides of the equation:
2. Now you must subtract the terms on the left side of the equation. Notice that the Least Common Denominator is "d". Then:
3. Finally, you can apply the Multiplication property of equality and multiply both sides of the equation by "b". So, you get:
17.6 because you do the working out backwards :)
