Camden Porter · Answer 1

X = 13

y=16

Work:

x+y=29

x=29-y

x+2y=45

29-y+2y=45

y=45-29

y=16

x=29-16

x=13

Abigail Ballard · Answer 2

x+y=29

y=29-x

x+2y=45

x+2 (29-x) = 45

x+58-2x=45

-1x=-13

x=13

y=29-13=16

x+y = 13+16 = 29

x+2y = 13 + 2 (16) = 13+32 = 45

so the numbers are 13 & 16
