Answer 1

Answer:

You take two equations and make value of any one variable same in both equation and then you subtract or add according to their signs. Then you get value of one variable. Then you substitute the value of that variable in any one equation to get the value of the other variable. Sorry if this is wrong

Answer 2

Substitute the value found for y into any equation involving both variables. Check the solution in both original equations. The solution is x = 1, y = –2.
