Solve the variable -7/9=D+1

1 answer

To solve for the variable D, we need to isolate it on one side of the equation.

Given equation: -7/9 = D + 1

First, let's isolate D by subtracting 1 from both sides of the equation:

-7/9 - 1 = D

To simplify the left side, we need to find a common denominator which is 9 in this case:

-7/9 - 9/9 = D

-16/9 = D

Therefore, the value of D is -16/9.
