Answer: m=6, m=-4
Step-by-step explanation:
To solve this proportion, we have to cross multiply.
Now that we have cross multiplied, we actually need to FOIL the left side to expand the equation.
Combine like terms.
We can move all terms to one side and then solve for m.
We can actually factor this to:
We set each factor equal to 0 to find m.
m-6=0
m=6
m+4=0
m=-4
For this case we have the following expression:
Since the denominator is equal, then we can add the numerator.
We have then:
Adding similar terms we have:
Rewriting we have:
Doing common factor in the numerator we have:
Factoring the denominator we have:
Canceling similar terms we have:
Answer:
The simplest form of the expression has 7 in the numerator and m+4 in the denominator.
