okay i got stuck on "5-x-x=-17"?
5-x-x = 17
5-2x = 17
-5 + 5 -2x = 17-5
-2x = 12
x = -6
I made mistake because 17 not positive
-2x = -17-5
-2x = -22
x =11
5 - x - x = - 17
5 - 2 x = - 17 Subtract 5 to both sides
5 - 2 x - 5 = - 17 - 5
- 2 x = - 22 Divide both sides by - 2
- 2 x / - 2 = - 22 / - 2
x = 11
Proof :
5 - x - x = 5 - 11 - 11 = 5 - 22 = - 17
Thank you so much!
To solve the equation "5 - x - x = -17", we need to isolate the variable "x" by combining like terms and simplifying the equation.
Step 1: Combine like terms on the left side of the equation:
5 - x - x = -17
5 - 2x = -17
Step 2: Move the constant term to the right side of the equation:
5 - 2x + 17 = 0
22 - 2x = 0
Step 3: Now, we want to isolate the variable, so let's move the constant term to the right side:
-2x = -22
Step 4: To isolate "x", divide both sides of the equation by -2:
-2x / -2 = -22 / -2
x = 11
So, the solution to the equation 5 - x - x = -17 is x = 11.
