Answer:
domain is equal to x. therefore, the domain is all of the x values. x = -6,-1,0,3
Step-by-step explanation:
Yes, it does. A good way to fill another 6 characters is with a "please".
Watch carefully:
You have said that 2x - 5 = 7
Add 5 to each side: 2x = 12
Divide each side by 2: x = 6 .
Answer:
x=-1, x= 1
