Question

Which of these is a simplified form of the equation 7y + 8 = 9 + 3y + 2y?

7y = 6
2y = 1
12y = 17
5y = 17

Answer 1

2y=1

Explanation:

7y + 8 = 9 + 3y + 2y

WE need to simplify it, try to get variable on one side and constant on the other side

7y + 8 = 9 + 3y + 2y

first we combine like terms

3y+2y is 5y

7y + 8 = 9 + 5y

Now to get y terms on one side we subtract 5y from both sides

7y -5y + 8 = 9 + 5y-5y

2y +8 = 9

Now we subtract 8 from both sides

2y +8 -8 = 9-8

2y= 1

Answer 2

put same forms to each sides
7y -5y = 9 - 8
2y = 1
