Answer:
x=5
Step-by-step explanation:
9-x-x=-1
Combine like terms.
9-2x=-1
Subtract 9 from both sides.
-2x=-10
Divide both sides by -2.
x=5
Answer:
Step 1: Simplify both sides of the equation.
9−x−x=−1
9+−x+−x=−1
(−x+−x)+(9)=−1(Combine Like Terms)
−2x+9=−1
−2x+9=−1
Step 2: Subtract 9 from both sides.
−2x+9−9=−1−9
−2x=−10
Step 3: Divide both sides by -2.
−2x
−2
=
−10
−2
