Question

What value of m makes the equation true?

[–6 + (–13)] + 8 = –6 + (m + 8)

m =

Answer 1

solve left side
[-6+(-13)] +8
(-6-13)+8
-19+8
-11

So you have to make the right side =-11

-6 +(m+8)=-11
m+8=-5
m=-13

Answer 2

do these things in THIS order and post your work here:

1: work out the value of the sum in the square brackets
2: Work out the value of the left hand side of the equation
3: Add 6 to EACH side of the equation
4:Subtract 8 from EACH side of the equation

That will give you the value for m

Answer 3

OR

just walk away with m=-13 having SOMEONE ELSE do the work for you
