n = -0.5714

Explanation:


{ \tt{1.8n + 0.2 = 3.2n + 1}}


{ \tt{1.8n = 3.2n + 1 - 0.2}}


{ \tt{1.8n = 3.2n + 0.8}}


{ \tt{1.8n - 3.2n = 0.8}}


{ \tt{ - 1.4n = 0.8}}

Divide both sides by -1.4 then,


{ \tt{ ( - 1.4)/( - 1.4)n = - ( 0.8)/(1.4)}}

Let us convert 0.8 to 8 and 1.4 to 14 by shifting the points. Then,


{ \tt{n = - (8)/(14)}}


{ \tt{n = - (4)/(7)}}


{ \blue{ \boxed{ \green{\sf{n = -0.571428571}}}}}
