How many solutions does the following equation have?

Question

3(y + 9) = 12y + 13

Answer 1

The equation is:

3(y + 9) = 12y + 13

Expanding the left side of the equation:

3y + 27 = 12y + 13

Subtracting 3y from both sides:

27 = 9y + 13

Subtracting 13 from both sides:

14 = 9y

Dividing by 9:

y = 14/9

Therefore, the equation has one solution.
