Eliezer Hogan · Answer 1

First you change it into slope intercept form.

Subtract y to both side.

-y-7=13

Then you add 7 to both side.

-y=7+13

Y can't be negative so you multiply - 1 to both side.

y=-7-13

y=-20

Alina Walter · Answer 2

Isolate y, so subtract 13 from both sides. 7 - minus 13 is - 20. So that leaves us with - 20 equals y.
