Question

-5 + 6d + 3 = 34 Solve

Answer 1

-5 + 6d + 3 = 34
+5 (both sides, cancels out on the left side of the "=")
6d + 3 = 39
-3 (both sides, cancels on the left)
6d = 36
/6 (divide six on both sides, cancels out on the left)

d = 6

Answer 2

-5 + 6d + 3 = 34
-2+6d=34
Add 2 to both sides
6d=36
Divide both sides by 6
6d/6=36/6
d=6

Check:
-5 + 6d + 3 = 34
Substitute d=6 into the equation
-5+6(6)+3=34
-5+36+3=34
31+3=34
34=34

Hope this helps! :)
