5X - 2Y = 22
X + Y = 3 => Y = 3 - X sub into first equation
5X - 2(3 - X) = 22
5X + 2X - 6 = 22
7X = 22 + 6 = 28
X = 28/7 = 4
Y = 3 - 4 = -1

5x - 2y = 22
x + y = 3
7x = 22 + 6 = 28
x = 4
y = 3 - x = 3 - 4 = -1
So
x = 4
y = -1

OK!
5*X - 2*Y = 22
X + Y = 3
5*X - 2*Y = 22
2*X + 2*Y = 2*3
Add the equations to get:
7*X= 28
X=4
X+Y=3, so, 4 +Y=3 ==> Y=-1
DONE!

Okay, so...
5x-2y=22
x+y=3
Now we start changing stuff around.
5x-2y=22
-2x+-2y=-6
5x-2y=-2x-2y+28
7x=28
x=4
5*4=20
22-20=2
2/-2=1
y=-1
The numbers are 4 and -1.

5a - 2b = 22
(a + b = 3) -----> multiply this by 2
----------------
5a - 2b = 22
+ 2a + 2b = 6 ---------> add the top with the bottom
-----------------
7a = 28
a = 4
therefore 4 + b = 3
and b = -1
