Simplify (8j3 − 10j2 − 7) − (6j3 − 10j2 − j + 12). a 2j3 − 20j2 − j + 5 b 2j3 + j − 19 c 2j3 − 20j2 + j − 19 d 2j3 − j + 5

okay wait before i answer, is this for your points on a graph?

a is the correct

exa:

)

3+11

14

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
