You can do operations on either side of the equation so long as they are equivalent.
In this case, it looks like you are trying to solve for d. That means you want to isolate it on one side of the equation.
To do that you first want to subtract 7 from both sides of the equation. That gives you:
2d+7-7 = 9-7 or
2d=2
Now, you can divide both sides of the equation by 2 to isolate d. So, you get:
2d/2 = 2/2 or
d=1

*subract 7 from each side
2d + 7 = 9
2d +7 -7 = 9 - 7
2d = 2
*divide each side by 2
2d / 2 = 2 / 2
d = 1

it is like this
2d+7=9
2d=9-7
2d=2
d=2/2
d=1
its simple yaar

constantly combine "like words" combine words like " 7 and 18 like "5x and 2x" in this situation: 7 - 5x = 17 we combine "7 and 17" 7 - 5x = 17 - 5x = 17 - 7 - 5x = 10 - 5x/-5 = 10/ -5 x = -2
