To find the value of d, you need to isolate it on one side of the equation. In this case:
16 + d = 20
To move 16 to the other side, you subtract 16 from both sides of the equation:
d = 20 - 16
Simplifying further:
d = 4
Therefore, the solution to the equation is d = 4.
use mental math to find the solution of the equation.
16+d=20
