Answer:
d = 105
Step-by-step explanation:
9d - 25 = 920
Bring -25 to the other side of the equation, which will become +25
9d = 920 + 25
9d = 945
Divide both sides by nine, so that we can cancel out the 9 with d, and find the value of d.
[tex]\frac{9d}{9} [/tex] = [tex]\frac{945}{9} [/tex]
d = [tex]\frac{945}{9} [/tex]
d = 105
