Hi there!


To solve 4d + 6 = 42, let's subtract 6 on both sides to isolate the variable.

4d + 6 = 42
       -6     -6
-----------------
       4d = 36

divide both sides by 4

        4d = 36
          d = 9

So your answer is d = 9.
Hope this helped!! :9
 4d + 6 = 42

Subtract 6 from each side
4d + 6 - 6 = 42 - 6
4d = 36

Divide each side by 4
4d 
÷ 4 = 36 ÷ 4
d = 9
