Answer:

m= -2

Explanation:

The solution is m = -2

Explanation:

The given rational equation is

We'll simplify the left hand side first.

The LCD is (m+4)(4-m)

Hence, multiply and divide the first term by 4-m and second by m +4

Use the difference of squares rule

We can now add the numerator

On simplifying, we get

Add the like terms

Multiply and divide left hand side by -1

We can cancel the denominator

Divide both sides by 8

The solution is m = -2
