Question

16 = –d + 6

Answer 1

subtract 6 on both sides
what u get?

Answer 2

16=-d+6

Since d is on the right-hand side of the equation, switch the sides so it is on the left-hand side of the equation.
-d+6=16

Move all terms not containing d to the right-hand side of the equation.
-d=10

Multiply -d by -1 to get d.
d=10*-1

Divide each term in the equation by -1.
d=-10

Hope this helps. :)
