Answer 2

Step-by-step explanation:

Simplifying

7n + 5 = 12

Reorder the terms:

5 + 7n = 12

Solving

5 + 7n = 12

Solving for variable 'n'.

Move all terms containing n to the left, all other terms to the right.

Add '-5' to each side of the equation.

5 + -5 + 7n = 12 + -5

Combine like terms: 5 + -5 = 0

0 + 7n = 12 + -5

7n = 12 + -5

Combine like terms: 12 + -5 = 7

7n = 7

Divide each side by '7'.

n = 1

Simplifying

n = 1
