Subtract ( 8e^(-x)) from both sides of the equation. ( e^x+2-8e^(-x)=0) Rewrite ( e^x) as ( ((e^x))^1). ( (e^x)+2-8e^(-x)=0) Rewrite ( -8e^(-x)) as ( -8((e^x))^(-1)). ( (e^x)+2-8((e^x))^(-1)=0) Substitute ( u) for ( e^x)...
Move ( 2) to the left of ( y).( e^x+e^(-x)=2y)Rewrite ( e^x) as ( ((e^x))^1).( (e^x)+e^(-x)=2y)Rewrite ( e^(-x)) as ( ((e^x))^(-1)).( (e^x)+((e^x))^(-1)=2y)Substitute ( u) for ( e^x).( u+u^(-1)=2y)Solve for ( u).( u...
