Full solution

Q. −40+2n=4n−8(n+8) -40+2 n=4 n-8(n+8)
  1. Distribute and Simplify: Simplify the right side of the equation by distributing −8-8 into (n+8)(n + 8).−40+2n=4n−8n−64-40 + 2n = 4n - 8n - 64
  2. Combine Like Terms: Combine like terms on the right side.\newline−40+2n=−4n−64-40 + 2n = -4n - 64
  3. Add 4n4n to Both Sides: Add 4n4n to both sides to get all nn terms on one side.\newline−40+2n+4n=−4n+4n−64-40 + 2n + 4n = -4n + 4n - 64\newline−40+6n=−64-40 + 6n = -64
  4. Add 4040 to Both Sides: Add 4040 to both sides to isolate the term with nn.\newline−40+40+6n=−64+40-40 + 40 + 6n = -64 + 40\newline6n=−246n = -24
  5. Divide by 66: Divide both sides by 66 to solve for nn.6n6=−246\frac{6n}{6} = \frac{-24}{6}n=−4n = -4
