Question

-2 2/3 + d/6 = 2/3
I am having trouble solving this equation.

Answer 1

d = 20

Explanation:

`\sf-2(2)/(3) +(d)/(6) =(2)/(3)`

First, make -2 2/3 as a improper fraction.

`\sf-(8)/(3) +(d)/(6) =(2)/(3)`

Add 8/3 to both sides.

`\sf (d)/(6) =(2)/(3)+(8)/(3)\\\\\sf (d)/(6) =(10)/(3)`

Now use cross multiplication.

`\sf3d=6*10\\\\3d=60`

Divide both sides by 3.

`\sf d=20`
