Question

4(2m-n)-11m+13n. First simplify then solve if m=-2 n=1

Answer 1

Answer:   15

Step-by-step explanation:

4(2m-n)-11m+13n ,  here substituting m = -2 and n = 1

We get, 4(2(-2) -(1)) -11(-2) + 13(1)

further solving this,

4((-4)- 1) + 11(2) + 13  =  4(-5)+ 22 +13 = -20 +22 +13 = 2 + 13

So, the equation simplifies to 15.
