Answer:

Step-by-step explanation:

If m = 5 and n = 3, then

3*(m-4)-n*(m-4) becomes 3*(5 - 4) - 3(5 - 4), or 3(1) - 3(1) = 0

Another way to do this would be to factor out m - 4 first.  We get:

(m - 4)(3 - n), and substituting the given values for m and n results in

5(3 - 3) = 0 (as before).

The answer is x = 6
Explanation:
First, you must assume that 5x-10=20. Next, you add 10 to 20, which makes the equation 5x=30. Next, divide 30 by 5, which then makes the equation x=6. When you substitute 6 in the original equation, it works, because 5(6)-10 equals 20.
