For these questions it's asking you to substitute the value into the equation.
For example question 5 says,
26= y-9;y=35

In this case: 26= 35 -9 is correct.
So your answer is true.

Answer:
If a<b, x<2
If a>b, x>2
Step-by-step explanation:
ax-bx>2a-2b, (a-b)x>2(a-b)
If a>b, x>2(a-b)/(a-b)=2
If a<b, x<2(a-b)/(a-b)=2
