Call the 1st number
Call the 2nd number
given:
(1) ( The sum of two numbers is 8 less than twice the first number )
(2) ( Their difference is 4 less than twice the second number )
------------------
Two or more equations is called a "system" of equations.
In order to solve, the number of equations has to equal
the number of unknowns. You have 2 equations and
2 unknowns, so it's solvable.
------------------
(1)
Subtract from both sides
(1)
and
(2)
------------------
Adding (1) and (2),

Add to both sides

and, since,

Add to both sides

The numbers are 14 and 6
------------------------
Note that for equation (2), if I had said
(2) , I end up with negative answers,
so I avoided that.
