The first six composite numbers are 4, 6, 8, 9, 10, 12. Their average is their total divided by their number.

... 49/6 = 8 1/6

Solve for y in 3(2y-4)=8y+9-9y
8090 [49]

3(2y - 4) = 8y + 9 - 9y

Distribute 3:

6y - 12 = 8y + 9 - 9y

Combine like terms:

6y - 12 = -y + 9

Add y to both sides:

7y - 12 = 9

Add 12 to both sides:

7y = 21

Divide both sides by 3:

y = 3
