Step-by-step explanation:
the first question
x-2/5=7
you need to use the same rules as pemdas but sorta in reverse. starting with multiplying 7 by 5, which is 35
x-2= 35
then you would add 2 to 35
making the answer x=37
You'd follow the same steps for the second one.
let me know if you have any questions
I hope this helped
Answer:

Of course! so basically for each value of x, for example -6, plug it into the equation. so for -6 do -2/3(-6)+7. hope this helps!
