Let x be the pot's price
Let y be the lid's price.
x + y = 11
x = y + 10 <-- plug y + 10 for x in the first equation and solve for y.
(y + 10) + y = 11 <-- combine the like terms...
2y + 10 = 11 <-- subtract 10 both sides of the equation...
2y + 10 - 10 = 11 - 10
2y = 1 <-- divide both sides by 2
2y/2 = 1/2
y = 1/2
y = 0.5
Now plug 0.5 for y in one equation and solve for x.
x = y + 10
x = 0.5 + 10
x = 10.5
So the pot (x) costs $10.50
The lid (y) costs $0.50
