Hello there!
To solve for z, first subtract 3 from both sides to isolate z/5:
z/5+3=-35
z/5=-38
Finally, multiply both sides by 5 to solve for z:
z/5=-38
z=-190
Now, to check if this answer is correct, plug -190 for z back into the original equation to see if you get a true mathematical statement.
-190/5+3=-35
-38+3=-35
-35=-35
Because -35 is equal to -35, your final answer would be z=-190.
Hope this helps and have a nice day! :)
