Apologies for the confusion. You are correct with your solutions:
n = 7 when solving the equation 26 - 2n = 12.
n = 2 when solving the equation 8n + 2 = 18.
n = 3 when solving the equation -10 + 6n = 8.
n = 4 when solving the equation 4n + 9 = 25.
To solve these equations for n, we need to isolate the variable n on one side of the equation. Let's go through each equation step by step:
1. 26 - 2n = 12
First, let's subtract 26 from both sides to isolate the term with n:
-2n = 12 - 26
Simplifying the right side gives us:
-2n = -14
To solve for n, divide both sides of the equation by -2:
n = -14 / -2
n = 7
Therefore, n = 7
2. 8n + 2 = 18
First, let's subtract 2 from both sides to isolate the term with n:
8n = 18 - 2
Simplifying the right side gives us:
8n = 16
To solve for n, divide both sides of the equation by 8:
n = 16 / 8
n = 2
Therefore, n = 2
3. -10 + 6n = 8
First, let's add 10 to both sides to isolate the term with n:
6n = 8 + 10
Simplifying the right side gives us:
6n = 18
To solve for n, divide both sides of the equation by 6:
n = 18 / 6
n = 3
Therefore, n = 3
4. 4n + 9 = 25
First, let's subtract 9 from both sides to isolate the term with n:
4n = 25 - 9
Simplifying the right side gives us:
4n = 16
To solve for n, divide both sides of the equation by 4:
n = 16 / 4
n = 4
Therefore, n = 4
So, the solutions for the equations are:
n = 7
n = 2
n = 3
n = 4
