Question

8n - (-2)/7 = 6

I have no idea how to go about solving this.

Answer 1

just think its -(-a) = a an identity.

also use the cross multiplication for 7 in the denominator. and solve for n

Answer 2

\[\frac{ 8n }{ 7 }=6 ; 8n= 6*7 ; n = \frac{ 42 }{8 }\]

Answer 3

8n-(-2)/7=6
multiply by 7,
56n-(-2)=42
56n+2=42
56n=42-2=40
n=40/56=5/7

Answer 4

Oh, I see, well thank you c:
