Y is at one side and the other terms in at the other side!

Answer 11

Is not it?

Answer 12

ohhh i see yes you're right. but idk how to get it that way for the second equation

Answer 13

We don't need that for the 2nd one.
Just sub. with the 1st into the 2nd as it is.
i.e replace every y in the 2nd eq. with (x-19)

got it?

Answer 14

not quite

Answer 15

2nd eq: 2x - y = 27

it will be: 2x-(x-19)=27

clear now?
