Solve for d. | - 2d|<10

Answer 1

 Your question: Find D in | - 2d|<10

==========================================================

SOLVING....

Solve the absolute value

|−2d| < 10

     =

−2d < 10

    or

−2d > −10

Solve −2d < 10 for D

Divide each side by -2

-2d ÷ -2 < 10 ÷ -2

d > -5

Now Solve −2d > −10

Divide each side by -2

-2d ÷ -2 > -10 ÷ -2

d < 5

So D is d < 5  and d > -5
