Question

Solve the equation.

7y−9=3(y+9)

Answer 1

Answer:

$7y - 9 = 3(y + 9) \\ 7y - 9 = 3y + 27 \\ 7y - 3y = 27 + 9 \\ 4y = 36 \\ y = \frac{36}{4} \\ y = 9$

Answer 2

$7y - 9 = 3(y + 9) \\ \\ 7y - 9 = 3y + 27 \\ \\ 7y - 3y = 27 + 9 \\ \\4y = 36 \\ \\ y = \frac{36}{4} \\ \\ y = \frac{ \cancel{ 36}}{ \cancel{4}} \\ \\ \boxed{ \sf y = 9}$
