Pls help !!! The sum of two numbers is 20. The difference between the same numbers is 48.
Write this system of equations and then solve it by graphing. Be sure to give the solution.

Answer:

34 and -14

Step-by-step explanation:

x+y=20

x-y=48---  add y to both sides to get x=48+y

(48+y)+y=20  (put 48+y in for x)

48+2y=20 (combine like terms)

2y=-28 (subtract 48 from both sides)

y=-14 (divide by 2)

x-14=20

x=34
