Solve the equation 9 equals negative d + 17

Step-by-step explanation:

1. substract 17 to both sides

2. know you have - 8=-d

3. divide both sides by - 1 in order to get a positive answer

4. total answer d = 8

Step-by-step explanation:

9=-d+17

(add d to both sides because it is the opposite of subtracting)

9+d=17

(subtract 9 from both sides because it is the opposite of adding)

d=17-9=8
