1. solve for one variable
x -y =12
x=12+y
2. substitute into the other equation
x+y=36
(12+y)+y=36
3. Solve for y
12+2y=36
2y=22
y=11
4. Plug in y into either beginning equation
x+y=34
x+(11)=34
5. Sove for x
x=34-11
x=23
6. Answer
X=23 and y=11

x + y = 34
x - y = 12 use elimination ((add the two equations together)) and you get:
2x=46 divide by 2:
x=23 plug that in to the first equation:
x + y = 34
23 + y = 34 subtract 23 from both sides:
y = 11
so your 2 numbers are 23 and 11

x+y=34
x-y=12
adding 2x=46
x=23
plugging in y=11
so the nos are 23 and 11 respectively
