First subtract 5x to move it to the other side.
Now you have y = -5x - 3. Now you can graph them. Here's what they look like graphed⤴⤴⤴
As you can tell from the graph above, this has no solutions because they don't cross paths.
You can also look at the second pic, to learn how to substitute. I hope this helps ya friend :) Good luck.

7a+16-3a-7= -11
combine like terms
4a+9= -11
add -9 to both sides
4a = - 20
divide by 4
a= -5
hope this helps
