7
Step-by-step explanation:
this is because 10-8 is 2 and 9-7 is also 2
Answer:
it's 7
Let's solve your equation step-by-step.
10−8=9−x
Step 1: Simplify both sides of the equation.
10−8=9−x
10+−8=9+−x
(10+−8)=−x+9(Combine Like Terms)
2=−x+9
2=−x+9
Step 2: Flip the equation.
−x+9=2
Step 3: Subtract 9 from both sides.
−x+9−9=2−9
−x=−7
Step 4: Divide both sides by -1.
−x
−1
=
−7
−1
x=7
Answer:
x=7
