1/3(y+7)=(y-1) y= what?

Answers

Answer 1
Answer:

Answer:

y=5

Step-by-step explanation:

1/3(y+7)=(y-1)

I will multiply by 3 on each side to get rid of the fractions

3*1/3(y+7)=(y-1)*3

y+7 = 3*(y-1)

Distribute the 3

y+7 = 3y -3

Subtract y from each side

y-y+7 = 3y-y-3

7 = 2y-3

Add 3 to each side

7+3 = 2y-3+3

10=2y

Divide each side by 2

10/2 = 2y/2

5 =y
