7y - 9 = 2(y - 4) + 1​

Step-by-step explanation:

7y-9=2y-8+1

7y-2y=9-8+1

5y=2 divide both sides by 5

y= 2/5

hope this helps

Step-by-step explanation:

Distribution comes first, so:

7y-9 = 2y-8+1

Then you simplify:

7y-9 = 2y-7

Then you subtract or add the lowest number with a letter:

5y-9 = -7

Now you get 5y alone, so we add the 9:

5y = 2

Then you divide 5y = 2 by 5

y = 2/5 or .4
