Answer: k = -1
2m = -6 that means m = -3
You can tell by dividing -6 by 2 to get -3
Now we know m = -3 let’s put that in the equation
3(-3) - 4k = -5
-9 - 4k = -5
Just try the option you have to figure it out. You know it’s not -3.5 or 3.5 because it’s a whole number so it wouldn’t be anything that’s a decimal.
-9 - 4(1) = ?
-9 - 4 = 13
Now let’s try doing -1
-9 - 4(-1) = ?
-9 - -4 = -5
