Answer:

1) Solve for x:

1/x + 2/y = 1

Change to standard for by multiplying each term by LCF xy:

(xy) 1/x + 2/y = 1 (xy)

y + 2x = xy

2x-xy = -y

Factor the left side of equation:

x(-y+2) = -y

Solve for x:

x(-y+2) = -y

x(-y+2)/(-y+2)  =  -y/(-y+2)

x = y/(y-2)

2.) Simplify:

(b)(b³) ÷ b+b+

= (b⁴) ÷ 3

= b³/3
