Question

Solve:
41 - 2n = -5(2n - 8)

Answer 1

41-2n= -5(2n - 8)

41-2n= -10n + 40 (open brackets)

take -2n to other side and bring 40 in its place. (change of signs take place when bringing to other side of the equation)

41-40= -10n+2n

1= -8n

n= -1/8 (standard form)

Answer 2

41-2n=-5(2n-8)
41-2n=-10n+40
-2n+10n=40-41
8n=-1
1/8(8n)=1/8(-1)
n=-1/8
