Ok, so the discount is given in a percentage, in this case 10%. The sale price is going to reflect 10% of the original price minus the discount, so...
Sale $ = original$ - original $ x .10
If we use some algebra, we can reorganize the equation to solve for the original price...
Sale $ = original$ - original $ x .10
Sale $ = original$ (1 - .10)
Sale $ = original$ x .90
original$ = sale$/.90
So now we can plug in our values
original price = 50/.90
original price = 55.55555 = $55.55 to the nearest nickel

Answer:
(5,20)
Step-by-step explanation:
2x + 2(4x) = 50
2x + 8x = 50
10x = 50
10x/10 = 50/10x
x = 5
2(5) + 2y = 50
10+ 2y = 50
-10. -10
---------------
2y = 40
2y/2 = 40/2
y = 20
