2(1-d)-(2d+1)

Jan 13th, 2015

Please, note that I solve this equation:

2(1-d)-(2d+1)=0

I apply the distributive property of multiplication, over addition, and I get:

2-2d-2d-1=0

and after a simple simplification, I write:

1-4d=0

so I add 4d to both sides and I will get:

4d=1

finally I divide both sides by 4, and I can write:

d=1/4

then your answer is: d=1/4
