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

• math -

correct the typo in 7x3y=-2

type each equation in a new line, so we tell where one ends and the next one begins.

• math -

7x3y=-2
-7x7x=14

• math -

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.

• math -

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