let 1 no be x
other no be y
x+y=15-2x
3x+y=15.....(I)
x-y=5-2y
x+y=5.......(II)
Solving I and II
x= 5 and y= 0
therfore two numbers are 5 and 0

Equation 1:
Equation 2:
---------------------------------
First you need to solve one of the equations for one variable.
I chose the second equation.
Equation 2:
Add B to both sides.
Subtract 5 from both sides.
--------------------------------
Now plug (3B - 5) into equation 1 for A.
Equation 1:
Simplify.
Combine like terms.
Subtract 4B from both sides.
Add 10 to both sides.
Divide both sides by 2.
Now plug 10 in for B and solve for A.
