✔ 最佳答案
n - 8 = -10
n= 8-10
n= -2
2009-07-07 4:14 pm
n - 8 = - 10
n = - 10 + 8
n = - 2

Answer: n = - 2

Checking:
- 2 - 8 = - 10
- 10 = - 10

n = - 10 + 8

n = - 2

n - 8 = -10
n= -10 + 8
n = -2.

When you move a negative sign over, it becomes positive.

ok, yes n does equal -2. to solve for n, you need to get it alone on one side. You always need to have something on each side of the equal sign. since we want to find n, you need to make your final answer (n=something). now since this is a -8, you add 8 to both sides. So,
n - 8 (+8)= - 10 (+8). on the left, the -8 and +8 cancle out. Therefor
n= -10 +8 or n= - 2. So if it is a negative number you want to get to the other side, you add. If it is a positive number, you subtract to the other side.

N - 8 = -10
add 8
N= -2
you need to have a number on one side and a variable on the other side of the equation. hat ever you do to one side you must do to the other side of the equation.

-2 is the answer

n - 8 = -10

add 8 to both sides
n - 8 + 8 = -10 + 8
n = -2
