Solve for n<br><br> -19=-8+n
laila [671]

-------------------------------------------------------------------------------------------------------------

Answer:  \textsf{n = -11}

-------------------------------------------------------------------------------------------------------------

Given:  \textsf{-19 = -8 + n}

Find:  \textsf{Solve for n}

Solution: In order to solve for n we need to add 8 to both sides which would cancel -8 on the right side and isolate n giving us the value of n.

<u>Add 8 to both sides</u>

  • \textsf{-19 + 8 = -8 + 8 + n}
  • \textsf{-19 + 8 = n}
  • \textsf{-11 = n}

Therefore, the final answer would be that n is equal to -11.
