Question

–4n + 7 + 2n = 1

Answer 1

Reorder the terms:
7 + -4n + 2n = 1

Combine like terms: -4n + 2n = -2n
7 + -2n = 1

Solving
7 + -2n = 1

Solving for variable 'n'.

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

Add '-7' to each side of the equation.
7 + -7 + -2n = 1 + -7

Combine like terms: 7 + -7 = 0
0 + -2n = 1 + -7
-2n = 1 + -7

Combine like terms: 1 + -7 = -6
-2n = -6

Divide each side by '-2'.
n = 3

Simplifying
n = 3
