solve for w
w -8 = 9
Try adding 8 to both sides.
could you show the formula please
There really is no formula for this.
All you must do is add 8 to both sides. What you do to one side, you must do to the other.
w-8 = 9
w-8(+8) = 9(+8)
The eights cancel out on this side. Now you are simply left with w = 17.
Make sense?
To solve for "w" in the equation w - 8 = 9, you can isolate the variable "w" by performing the opposite operation of subtracting 8, which is adding 8, on both sides of the equation.
Let's go step by step:
1. Start with the equation: w - 8 = 9
2. Add 8 to both sides of the equation to isolate "w":
(w - 8) + 8 = 9 + 8
Simplifying both sides:
w - 8 + 8 = 17
The -8 and +8 cancel each other out on the left side:
w = 17
Therefore, the solution to the equation w - 8 = 9 is w = 17.
