Ayden Vazquez · Answer 1

X=y+4

x+y=20

now substitute the x for (y+4) in the second equation

(y+4) + y=20

2y+4=20

2y=16

y=8

now substitute 8 for y in the first equation

x=8+4

x=12

so y=8 and x=12

Emmanuel Ramsey · Answer 2

The two numbers would be 12 and 8 because 12 is 4 more than 8 and so the sum of 12 and 8 is 20.
