can someone explain step by step to do math problems for to solve the system ill use an example 7x3y=2 7x7x=14

correct the typo in 7x3y=2
type each equation in a new line, so we tell where one ends and the next one begins.

7x3y=2
7x7x=14

this is worse than before, now I have to read it as
21xy = 2
49x^2 = 14
it can't be that, since the second equation clearly has no real solution.
I have a feeling you meant to type
7x + 3y = 2
7x + 7y = 14
but until you clarify the equation, there is no point in working it out.

7x + 3y = 2
7x + 7y = 14
