use mental math to find the solution of the equation.

Question

16+d=20

Answer 1

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.
