9 + x = 17
I know that x=8 but how did you get it
Thanks
9 + x = 17
Subtract 9 from both sides of the equation.
9 - 9 + x = 17 - 9
x = 8
Remember -- you need to get the known quantities on one side and the unknown on the other side.
thanks so much!
You're very welcome.
To solve the equation 9 + x = 17 for x, you can follow these steps:
Step 1: Start with the equation 9 + x = 17.
Step 2: In order to isolate the variable x, subtract 9 from both sides of the equation. This balances the equation:
(9 + x) - 9 = 17 - 9
x = 17 - 9
Step 3: Evaluate each side of the equation:
x = 8
Therefore, the value of x that makes the equation 9 + x = 17 true is x = 8.
