Question

what is the answer to 2d-4=8 to algebra in math

Answer 1

2d - 4 = 8.

 

Think about what you might do ('legally') to isolate the variable (d).

 

First, add 4 to each side.  Then you will have an expression giving the value of 2d.

 

The final (not too hard) step will be to divide both sides by 2, thus solving for d itself.

 

Algebra--VERY LOGICAL!
