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
