# Thread: How could i solve?

1. ## How could i solve?

How could i solve this?

800 + 12N = 1000 + 10N

2. 1. subtract 10N from both sides

2. subtract 800 from both sides

3. divide what's left by the coefficient of N

How could i solve this?

800 + 12N = 1000 + 10N
Subtract 10N from both sides:

800 + 12N - 10N = 1000 +10N-10N

800 +2N = 1000

subtract 800 from both sides

800+2N-800=1000-800

2N = 200

Divide both sides by 2

2N/2 = 200/2

N = 100.
