y=1

____________

since you have the value of y u can plug it in in either of the equations.

7x+5(1)=19 step three

____________

7x+5-5=19-5 step four

____________

`(7x)/(7)`=
`(14)/(7)`

x=2 step five

____________

You can check whether the answers are correct by plugging them back in.

7(2)+5(1)=19
