5+3=4d please help me

So the object of this problem is to find out the value of d.

To do this, first think about 5 + 3. This equals 8, right? So the value of d times 4 has to equal 8.

No other number besides 2 would make sense. 2 would equal d because 4 x 2 is 8, and 5 + 3 is 8.

So you would write the answer as:

5+3=4(2)

First, add '5 + 3' to get '8'.


Second, divide both sides by '4', leaving the 'd' by itself.


Third,  (8 ÷ 4), simplify the fraction to '2'.


Fourth, you can switch your sides.
