x + y + -5 = 2X
X + Y = 29
Do a bit of switch o roo....Y-5 = x..sub into second equation
Y-5+ Y = 29
2Y = 34
Y = 17
X =12

Let x= the first no.
therfore 29= x + (2x + 5) or (2x + 5) + x = 29
3x + 5 = 29
3x = 24
x = 8
Test it: 16 + 5 + 8 + 29

x + y = 5 + 2x ==> -x + y = 5. x + y = 29 ==> 2y = 34, y = 17. x = 12.

x + y = 2x + 5
2x + 5 = 29
2x = 24
x = 12
12 + y = 29
y = 7
