Question

solve for n:
2m - n = 8
options:
n = 2m - 8
n = -2m - 8
n = -2m + 8
n = 2m + 8

Explanation:

Step1: Isolate -n

Start with the equation \(2m - n = 8\). Subtract \(2m\) from both sides:
\(2m - n - 2m = 8 - 2m\)
Simplify the left side: \(-n = 8 - 2m\)

Step2: Solve for n

Multiply both sides by \(-1\) to solve for \(n\):
\(n = -8 + 2m\)
Rearrange the terms: \(n = 2m - 8\)

Answer:

n = 2m - 8 (corresponding to the first option: n = 2m - 8)
