Mathematics: An error is made in solving the equation below. what is the correct solution to the equation? 50 points plz ! 5(x – 5) = 15 5(x – 5 + 5) = 15 + 5 5x = 20 5x ÷ 5 = 20 ÷ 5 x = 4 –50 –2 8 80

It was not my intention to post that answer, as it does not solve the question, but hope it helps somehow. Step-by-step explanation:You want to verify this identity.The common denominator is Solving the first and second numerator:Now we haveOnceAlso, consider the identity:That last claim is true....

Step-by-step explanation:

$\text{b)} \frac{\sin(a)}{\sin(a)-\cos(a)} - \frac{\cos(a)}{\cos(a)-\sin(a)} = \frac{1+\cot^2 (a)}{1-\cot^2 (a)}$

You want to verify this identity.

$\frac{\sin(a)(\cos(a)-\sin(a))}{(\sin(a)-\cos(a))(\cos(a)-\sin(a))} - \frac{\cos(a)(\sin(a)-\cos(a))}{(\sin(a)-\cos(a))(\cos(a)-\sin(a))} = \frac{1+\cot^2 (a)}{1-\cot^2 (a)}$
