Equations
We are solving the equation
1-2n+5=10
It means to find the value of n that makes equality be true.
Let's go step by step
First, we add the numbers in the left side 1+5=6:
6-2n=10
Now we subtract 6 on both sides:
6-2n-6=10-6
Operate again:
-2n=4
Finally, divide by -2:
n = 4 / (-2)
Operate:
n = -2
The solution is n = -2
